How to deal with frustration during a game?

With this question I seek something that is more of psychological advice from exoeriences players. When I play online on chess dot com or elsewhere I can sometimes find my positions in such an arrangement that I simply do not have (or do not see) any moves that would rescue me from loss of pieces or generally in a bad state. I become frustrated. Not exactly angry, but frustrated with myself and I am not sure how to get positive or useful lessons out of such situations.

Do you recommend resigning such matches, or to keep playing closer to the end? Maybe you have some other advice on how to deal with this tension?

You should post an example of a position where you felt this.  Obviously, there are positions where you should fight on and others where you should resign. As you study and play more, your ability to figure out a plan will improve.

Your own profile reveals:

I was taught to plat chess in childhood and have played it only casually with my father and grandfather. Haven't really played chess ever since I started high school, haven't played in college, recently at age thirty I began playing again. This is a hobby I keep for enjoyment, not for competition.

I am probably more I terested in chess history and different chess variants than in becoming very good at it.

You've been a member for a little over a year. Does this attitude from your profile still hold?  There's nothing wrong with it. I'm just asking.

personally I accept the fact I'm not going to win every game. at some point a loss is inevitable or it wouldn't be a game people would find challenging to play. Each person has to decide for himself at what point when to quit. I'm the stubborn sort, and won't quit no matter how bad I lose. The only exception is when I make an obvious blunder and I am beating myself. I have rescued many lost games by fighting back and I have to admire the guys skill if he can knock me down quickly. you can learn a lot by playing it out. it is a matter of patience, try to complicate the game, and stay alert for opportunities.

@notmtwain I have actually only been a member of this site for about two months. If you're referring to attitude toward chess as a hobby and not for competition then yes I still hold that view. I guess I should have specified that by "not for competition" I mean that I don't compete in events anywhere. I still like winning.

The only thing to do with good advice is pass it on.... :D

Some people play with their increments!! I dont advise it!!!!

The only possible solution is to read and eternalize Epictetus "Enchiridion" (with the option of adding his "Lectures".) It works, they use it in the US army in which frustrations are plentiful.

Drink bleach!!

I think it's better to resign and move on.  Slowly after getting those bad positions again and again you'll learn to avoid them ahead of time.

That's just my philosophy and i'm not experienced.  I play purely for fun (and beating people senseless of course).

   I'd very much recommend, as a general guide, that you play on; as more often then not the position can be salvaged, by time-trouble, blunders, (or a combination of the two) -- and, sometimes, the position might have merited a sacrifice (or two) in the first place if you get creative. 

 So when faced with a blunder, I think, the best thing (for that game) is not to dwell overly long upon it and simply accept the deficit in a positive frame of mind - by playing the strongest continuation - even if that means losing a piece or more, or just by having an objectively worse position. By making your opponent work for their win, not only might you rescue the game (it's hard to win winning positions), but you'll practice the skills needed for imbalanced positions, and the tactics that they pose. I also think that continuing on can also help build confidence in future games, when important sacrifices have to be considered; knowing that, if it back-fires, you can put up a long and stubburn resistance, with ease, is a useful resource to have.

 I've tried to write down some general principles I try to adhere to, when faced with the situation you describe:

 (i) First and foremost, I try to get all my remaining pieces extremely active as fast as possible; for instance, if you can keep, and mantain, a lead in development, then the deficit in material is temporarily nullified. Long-term you'll probably be losing, so keeping pawn structures intact, is probably going to be less useful then having pieces posing threats - but this is certainly subjective to the specifics of the game.

 (ii) Instead of focusing on the mistake, focus on posing as many questions to your opponent as possible - ie. generate threats. Look for checkmating possibilities and other kinds of tactics; even if they can be met, and you can't see a continuation where you can save the game, your opponent still has to find those answers - and that may take up a lot of time on his/her clock.

 (iii) If there is a very forcing best-line, then it is often advantageous to pick it; it will usually afford you the chance to pre-move and gain even more time per move over your opponent.

 (iv) Pause -- don't let the frustration bite, and make a move in haste. I always try to get myself in the right frame of mind to continue - even if that means looking away from the board for a while. If you can return with a fresh perspective, and mindset, then all the better. Look at the positives in your position, and take it from there; literally -- take stock of everything that you like on the board, and convince yourself that they can - and do - compensate for your predicament, somehow. 

 I've had recent games where I've played an attack poorly, only for the blundered piece to then lead to a mate; for example in the game below, I couldn't see a way to win back the piece, or keep up my momentum, but I played on, and won the game, by getting my pieces active - and forcing a blunder.
