Is it possible to become GM without coaching ?

I am not trolling. I am serious. I was removed from college recently. If you want to know the reason, message me personally. I cannot post here because some of my friends might read it and they will tell everyone near me and my reputation will be spoiled.
I have not the slightest interest in knowing why a random person on a chess forum was removed from college. I am just trying to help you be more realistic. You don't yet seem to know enough about chess to realise how difficult it is to become a Grandmaster, or what an amazingly high standard it is.
It is not something you can plan to become while you are still a not-especially-strong player. If you make plans like that you are deluding yourself, and wasting your time.
It (the GM title) is something that you might achieve if you have the right combination of genetic endowment (if such is needed), early enough start, live somewhere where you can get strong opposition, have the luck to avoid lumbering yourself with bad habits from the start (this is one area where a coach can help) and sustain the right sort of hard work for years.
It is like athletics and other sports. You cannot plan to be a be 10s 100m sprinter until you are already running 10.5 or better, and for most of us 12s is already an unreachable dream; you aren't going to challenge MIchael Phelps if it takes you 20s to swim a 25m length (although that is respectable for a recreational swimmer); you can't plan to be a top-100 tennis player if you aren't even the champion at your local club; you can't plan on becoming a premier league player when you are barely good enough to play in Sunday League ...
... etc.

I feel that I am inclined to give fair warning on threads like this. You see, the chess.com community doesn't take too kindly to somebody attempting to become GM. Perhaps they're just jealous of your capacity for chess learning, and commitment. Folks here can sure be hostile towards anybody trying to reach their full potential. Just see my thread for example. Vicious stuff.

You are wrong. You are smart enough to correct yourself. All you need do is use your undoubted intelligence to work it out, rather than for making impossible plans (if you are serious) or trolling the forums (if you aren't serious).
I would encourage you to stop calling everybody a troll, and try to seek value in this deep intellectual discussions. I'm sure you have some good points to add without being so ConceitedAndRude.

Let's see. There is lot of time remaining . I am only 22 years old now. Imagine how strong my game will be when I become 44 years old if I keep studying and playing chess everyday for atleast 4 hours !

Kasparov learned Chess when he was 7 and he became World Champion at 22 years old. It took him 15 years of intensive study with strong top soviet coaches to become World Champion, and it took him 29 years to reach his peak rating.
He made it to Chess Master (Soviet Union title) in 1978, which I guess is the same as GM now, so it took him 8 years to become GM, being a child, and working in Botvinnik's school since he was 10.
You on the other hand are already 22 years old, should be working for your own food, and I doubt you will ever study chess intensively with top coaches for more than 8 years (you are no longer a kid so learning chess will be harder for you).
I like what the CM Coleman said, get a job/study, and then worry about chess, no doubt you can become a very strong player if you play for 22 years but not a GM, not when real life hits you and you need to start working/studying/worrying at other things.

How do you know that M&P (or anyone else you would be willing to tell discreetly about the reason you were removed) isn't one of your friends, who joined this site anonymously?

Thought this was some sort of troll thread but it looks like you are very serious regarding chess. If you are willing to spend the time, get yourself a coach. If you don't get along with a coach, then sign up for any online chess training that is structured. I am enrolled in one and it has done some improvement in my play. Unless you get some help, you will be continuing to play/analyse/visualise/think the wrong way.
Also keep your expectations to what you can achieve in reality. Chess is not "Law of attraction". Start with setting a target to cross 1800 ELO in next X months, and then reach 2000 within X years and so on. Good luck!

And last but not least, always play opponents rated higher than you. You will loose more games. Analyse them and you will learn a lot in the process.

The problem here is that he god thrown out of college (lol) and will starve himself if he thinks playing chess instead of getting a job is a good idea.

If you treat chess like a job there is no reason why one cant reach the top. I'm studying my butt off just now and hope one day to give up the 9-5 to live the dream as a professional chess player.
Get to 2200+, start a youtube channel and stream blitz live. If you can talk non-stop with a dry sense of humor you will get many subscribers (resulting in more views, and $$). Like how I am addicted to GM Jan Gustafsson's youtube videos. Classics they are.

Are you guys all stupid?
Getting to 2200 requires WORK. And you need to eat, pay tournament fees, pay for books, coaches, etc... Which means less time for chess.
2Q1C is joking, or at least I think he is. You just cant take chess as a job and magically become good at it.
Would I be able to be Michael Phelps if I decided I dont want to study anymore but instead swim every day?

Yeah, and do you think you could be Macer75 if you just woke up one day and decided, I'm going to have a try at trolling?

I could, and I could probably do it better. However my morals dont allow me to do so, I cant simply spam my own threads blatantly like you do, Ill leave that art to you.

No, you are the only dumb thing here. And you know it. Just as with swimming you need both time and talent to excel at a "brain game".
You dont need to be the sharpest tool in the box to get a decent level of chess, thats true, but you do have to be the sharpest tool to become the World Champion, or a very sharp tool to become GM.
Ambition needs not respect anything. There's no disrespect either. There may be poor expectations, naivete and/or ignorance, which make themselves clear with time. Nothing to worry about; everyone learns in their own way.
But until it eventually happens, it's impossible to prove that it's impossible. And that's a great thing.
So why should anyone give a flying crap about preceding status?
Limits are meant to be broken.
You need to get back into college, you won't make a living from chess.
