Having some self esteem issues :(

So I’ve been on an all time high when it came to my self esteem, but recently ive been plummeting. I’ve always had issues with the way I see myself but usually I get over it. Anyways, ive just been down. I feel like I can’t do anything right, I have no talent at all, and that there’s no point to trying. So I figured I’d try to get into something to keep my mind off of that, something that takes time. So I thought of yoga and gymnastics, stuff like that. I started with something easy, a goal. All I wanted was to be able to stand up from a bridge (I think it’s called a backbend but idk). I’ve definitely made some progress over the past 3 days. So I told my friend (who’s in cheer) about it and she acted as if it was the stupidest idea ever, and then she started bragging about all the stuff she could do, which made me feel like crap. Which obviously didn’t help with my belief that I have no talent. Which tbh I really don’t. I usually lose motivation even when I am decent at something. I wish I could try harder but I can’t. It just feels like I’m worthless sometimes 😪
