Ah, apologies!
In that case, I, well, that's a bit hard.. You might be able to find something that you find fun but are unable to get good at ?
For a while, I played the game Osu! Because I really couldn't get good, but it was still a lot of fun for me.. I still play once in a while, and while I'm a lot better than I used to be, it's very clear that there's no chance for me to ever "get good" at it :)
Painting is another such activity.. But, maybe the important part is that you find something in it that you enjoy, even if you'll never do it very well :)
