losing games because of anxiety. Help!!!!

as you guys can see in step 29 i made a blunder which made me go from winning to losing position actually my heart started throbbing at that position , yes i do have anxiety as an issue in my life but i didn't effect my game until i reached 1000 rating 

thank you from deep of my heart thank you

past experience of not checking the king and loosing game

18 minutes on his clock 12 minutes 

i just screwed it up because my heart was throbbing 

the best thing to do is concentration on the game, when you step on the board make yourself a different being with no relation with your personal issues because that can be a real psychological killer, and this is hard to do i hope you get better soon.

Bcz of anxiety, my rating was dropped by 200 points.So I highly recommend you to take rest. playing will just worsen your game

Thank you chronos its just i have developed this habit of urgency to respond in 2-5 seconds because  some of my opponents have cursed me in the past for playing it slow from 1-3 minutes in rapid . I need to get over the fact that i should stop caring about what my opponent thinks about me as a person and also get over what they are saying 

Thats lovely advice

yeah i will take a break for a week 

so true

I'm going to do something risky; I'm going to disagree with Deirdre! (It's okay, I'm only going to disagree a little bit. )

I don't like the concept of discipline as fighting yourself. This way you are fighting two opponents: yourself, and the obstacles in the way of achieving your goal, and the fun can, unless you are a certain type of person, drain out of the activity. Instead, I believe in working with yourself. 

William, do you mean? How can you be disciplined by not regulating your own thoughts and pruning unnecessary data? Well, first, I want you to understand that I have not completely ascertained the answer to that question. I'm still learning! But I believe the answer lies in a relaxed state of mind.

If you have studied properly (a whole different beast), you have assimilated that information. It is in the database. Saying "GRR, I know this, GRR, THINK brain, THINK!" wastes a lot of energy, and is actually very distracting. (Trust me, I'm an expert at overthinking and distracting myself. Worse is when you catch yourself doing it and say "GRR, don't think about thinking, just do it GRRRRRRRAWR" and frustrate the stuffing out of yourself. When this happens, it is time to take a break, simple as that.) 

However, and this is the stage where I am stuck at the moment, you must make proper thinking a habit. This is quite difficult, and it is easy to get frustrated with yourself when you drop pieces despite having done all the studying in the world. For some people like Deirdre, it seems to work to just muscle through. For me, though, when I find myself properly relaxed and composed, my instinct and my thought process is often enough for me to play at my very best, all on its own.

So, to summarize:

1) Train good habits Make sure to study master games, mixed with games of 1500s, and while you're doing it, look for undefended pieces or pawns. This is all I want you to do for now, weak squares and superior/inferior pieces can come later. (If you see them, all the better, but not yet.) Take all the time you need to start off, and if you have to, start at the a file and work your way through the b file, c file, d file, etcetera, and identify all of the undefended bits. If you do this, you'll find it easier to eventually recognize them quicker, and quicker, until it's all instinct. (Sometimes you will have off days, and that brings us to the next point.) Btw, I still have to work on this too!

2) Know when to stop There's no worse feeling than that accursed haze, when you feel like you can't see anything, you keep making silly mistakes, but you just want to win ONE game. And you just feel miserable; every piece you hang feels like another nail in the coffin of your chess ambitions. 
This is time to stop. Just stop. Walk away, drink some water, forget about chess. Because that behavior is training habits that are destroying all your good training work. 

I just want to clarify, everyone makes mistakes from time to time, especially when we're at your level. Beating yourself up after every mistake is impractical. But I'm referring to when it starts to affect you emotionally; not only is it miserable, it's bad for your chess too.

3) Be patient with yourself This I think is important. Remember, you're on your own side. This can be hard to remember, especially when one is struggling with anxiety (been there, done that, not fun) but I think this is one of the most comforting things to recognize. I'm not saying, make excuses for yourself. But be frank. "Okay, I made a mistake. I'll try not to next time. Now, what can I do with what I've got left?" As opposed to, "You fool, why are you even playing this game?"

As I said, I'm still working on this. Find what works for you, but remember you're on your own side. Hope I helped.

The best chess I played was in an OTB rapid tournament, where I tied for first. I felt nervous as blazes; I was playing people rated 300 points higher than me, who I'd previously been creamed by. But this time, I decided to do something different. Instead of stewing in my own anxiety, I rode the emotions; I let myself feel as anxious as I needed to before the game, then I turned my attention to the chess when the clock started. And when I felt myself start to get eager when I felt I was superior, I went with the flow instead of trying to repress it, but I was conscious that that was not a good time to make a move. 

I think we may be saying similar things, just from two different perspectives.
