I have always suffered from social anxiety, how can I get past this in Destiny?

Hi! I recently picked up Destiny 2 and have been enjoying it a ton since around mid-Season of the Chosen, I picked up all the dlc and even the deluxe edition of beyond light because I had extra money to throw around, although I have hit a barrier in the game's content now. I've always had severe social anxiety and it took me a while to even start queueing for the default strike playlist out of fear of being a bad teammate, I've gotten past that but now I'm at the point where queues with matchmaking off is impossible to do, I've only been able to do lfgs for Prophecy because I was taught how to do it and trials because it's suicide fireteams. I'm really looking into trying the raids and anything above Hero difficulty nightfalls because I feel like I'm ready for some of the endgame content, but I don't feel like I will be contributing much to a fireteam if I join and thus never try lfgs, I also feel like the mechanics in raids are a bit overwhelming and I would hate to cause my team to wipe and fail an encounter several times

How can I get past this issue? I would really like to enjoy the game to it's fullest but I can't seem to be able to
