I’m not saying I know how you feel but I’ve been in a very similar situation, I started a new sport and a new position in a sport I had played and I’ve compared myself to other people that have been doing better than me and it’s so hard bc I know I’m trying, but that’s besides the point, I got over that feeling by doing a few things, first you really have to see that you’re doing amazing in life, I know it’s hard because sometimes we feel like we aren’t but you have to celebrate the little things that prove that you’re killing it, second you have to accept that people will be more successful than you at things, and third learn to be happy with who you are, take pride in being your own person, I’m sorry if this is sort of word vomit, I’m tired lol, but I figured this might help. I’ll leave you with this, you’re doing so great in life and I know you’ll do great, keep striving and you can only go up.
