I can't play online games without feeling like I'm letting everyone down

I've been trying to get into GTAV Online, but as soon as it requires the players to work as a team I either chicken out before the game even starts or quickly quit the game after the first fail because I feel so embarrassed. I know that I need to actually play the game to develop any skills but any failure that is witnessed by other people makes me want to die of embarrassment. I feel like I'm ruining the game for everyone.

I'm so useless when it comes to simply having fun. I can't do it. I feel like I'm invading other people's lives with my failures

Also, from time to time there are some people who try to communicate with me but that makes me even more scared. Today someone team-messaged me saying hi and it made me quit the game. I don't know what to do. It seems like I want to reach out to people but run away when someone is actually willing to suffer my presence.
