No hobby seems fun

I'm tired of searching for a hobby constantly. I always do something for a while and then all of a sudden it's not fun anymore. There's something wrong with me. I have a lot of free time now and I do almost nothing. I just talk to people. I think a part of the issue is that I'm scared of being bad at something (which is inevitable if I'm going to start something new). I'm not sure though, it could be some other issue. Does anyone have this experience and if so, did you manage to solve it and how?
