i want to injoy chess again

I have a simple goal, Get to 1000 elo. I've had this goal for about 4 years now and have been hard stuck at 700-800 for most of that time.  My biggest problems are that i give up to easy like 80% of my losses are resignations where i blunder pieces or get out played and just give up. These losses make me feel stupid and make me angry. i just want to have fun again and not take losing so personally. I know i shouldn't make a number my goal and instead should focus on improving but each loss each mistake leaves me so bitter and going back to see where i messed up is like a slap in the face and a reminder of how stupid i am. How do i fix this? how do i turn losses into a learning experience instead of getting angry?

At least you have more than me , I only have 300, I would be sooooo happy if could get 700 or 800

Totally agree. I’m stuck on 650 for ages. Sometimes those blunders are forced by previous seemingly innocuous moves. I’ve got this feeling ~750 is when people is able to think one good move at a time (or very basic 2-move strategies) and above that elo is when people start thinking stronger and less obvious 2+ moves ahead.
