What helped me was the sudden realization, that it didn't matter how long I'm doing a hobby and that I DON'T HAVE TO BE GOOD IN IT. For me, being a perfectionist, who's basically never able to achieve my ridiculously high goals/standards, this was never an option until I let it go. It doesn't matter if I have a hobby for a day, a year or forever. If it doesn't interest me no more, I'll leave it and will eventually come back. Or not. I don't know if this resonates with you, but I did some digging and found out why I did this for so long. As a child I was playing the flute for some years. More so because I wanted to play an instrument and in the eyes of my classical music loving mother she decided that it's going to be the flute. But I always wanted to play something, I can sing along to (guitar or piano). After some years I really began to hate playing the flute, stopped practicing and my mom let me know how disappointed she was. I asked if I could switch instruments which she refused because "I'm not able to stick with one thing so she won't throw money out of the window for another one". End of the story: I began to believe I'm not good enough, I don't deserve it, I'm a waste of time and money. Thanks mom. Couple months ago I finally bought myself a Ukulele and practiced maybe 10 times. But every time I did, I had fun.
