I feel this way about music. When I was in high school I would compose loads of songs for many musical groups and a lot of members of my favorite bands at the time told me I had a real knack for composition, even at age 14-15. Unfortunately I composed mostly when I was hypomanic or hyperfocused and after a big depression I just couldn't get back into it. My own band fell apart because of my depression and I couldn't get the motivation to keep going with it. I haven't composed a single song since high school. I rarely even play the 8 instruments I can play. I don't even know if I can still play them properly.
