Stuck at 400 ELO and I've been playing for a year.

yea he did

 to get a higher rating, watch gothamchess with extremely high levels of orange juice and put a toothpick in your mouth

(or, just.. do puzzles and lessons)

Take toothpick in ur back hole.

I mostly use the wayward queen attack, I'm also 400 elo and most of the times I win with that opening,how it helps

im stuck in the 500's yet when i started chess.com i was in the 600's how have i only gotten worse. right now i do the  Nimzowitsch-Larsen Attack followed with the sicilian. is that good or should i change my opening???

Its funny im stuck at 500's yet i beat people who are in chess clubs at my school and other friends that are above 500's

as a 1100 that has gotten there in around 3 months starting from 500, i'd say that you should literally just follow opening principals and dont attack too early, opponents can easily counterattack and now you have a piece doing absolutely nothing and you're in a bad position. 

at the 400-500 level only play 10 minute rapid games and really take your time to stick to the principles, if you find a tactic then cool play it. whenever you lose, review the game. chessbrah's building habits series is really good for this level. make sure you check out the extras to see even more examples on how to play well. relax and have fun, it's very important to have a good state of mind when playing.

(i found the first two videos to be espesially helpful and didnt really bother with the others)

puzzles are also pretty great for improving but shouldnt be your main priority until around 600. in addition, if you do find a tactic, always DOUBLE CHECK them. a tactic i love in some of my games was trying to do some sort of sacrifice then forking a bishop and knight with a pawn but i sometimes mistakenly let my bishop hang and now im down a piece.

i also really like just watching some instructive chess content and trying to guess what might be the next move. always ask why they made the move.

play lots of games! never resign and don't be scared of losing rating points. have a good day

but i do admit that i have a lot of time on my hands, so it may take a bit more time for you to improve if you dont have as much. aaand i almost forgot that you should watch some video on important chess terms so you will actually know what people are talking about when they talk about them. also learn traps, not to play them but to know how to deal with them. have a great day once again.

1. develop pieces

U do capitalize on people's blunders but you could work on not blundering an do try planning ahead a few moves.. you could work on defense guarding your pieces better.. I see you dropped a 800 ranked player after he left his queen open nice game

Reading something does not make it true. Nor does one persons experience. And it certainly doesn't mean you are qualified to go around claiming it is facts.

It depends on the definition of "blunder". Don't define it as a computer (every bad move). Define it like this: a blunder is a move that is obviously bad even for the player who plays it. For a player under 500, this is pretty much only when you just hang a piece. Spotting simple tactics comes later.

Some of the players under 300  should be rated 1000 or 1100, am I the only one who gets these players?

Reading all this, I've came to a conclusion.
No, as a 400 rated player, even if you do play puzzles, learn from the 3 or so useful lessons on chess.com (Just go to Lichess, there's a massive amount of UGC lessons called studies.). I understand the mindset, you see a good move, but here's the problem; most of my games I do a tactic, don't look and immediately lose 3 points of material.
How do I fix this? Well, obviously, look. But, for some of you, that's hard. Considering I play blitz and study only a few times a day, I'm still at 450. Why?
Well, my fellow 400 players, here's what you have to learn;
Spot tactics, learn openings that give you a positional advantage over a material one (e.g: Halloween Gambit, Bongcloud Attack and a few more that I'm missing out on.)
To spot tactics of course, you need to look at the whole board. You might've heard to look at the whole board, but, if you cant do that, I suggest doing a simpler, though less effective, looking-at-the-pieces-and-where-they-can-take/move approach.
Learn a variety of openings, how to counter them and such. The Polish opening has moderate success to noobs, but it is a good >1000 Elo Queen Pawn counter.
TL;DR: For short term Elo, learn gambits and such. For long term, learn counters to popular openings. Puzzles will only put you at a disadvantage depending on the skill level.

im 1200 and i can teach and make you a 1200 if youre interested message me and we'll talk

So I don’t think I’m bad because I can beat 800s but I’m 300 because I use this as my school account and I have to resign…. A lot

I don't understand how you are having issues. You're over 1000 elo and only played 84 games. I'm just below 400 elo and I have player 470 games.
