Hi bluedonna92,
I'm so sorry to hear about this and I can relate. I experienced something similar. I play piano for years and I used to songwrite and compose my own music. Composing and songwriting means a lot to me. It is literally a part of me. I even wanted to pursue a music career...but right now, I'm not even songwriting or composing anymore. I just lost interest in it and I almost lost interest in music...even playing the piano. Just like what you did, I attempted to regain my interest in music. But all attempt didn't last long. I felt like it's a chore. I lost my sense of self too.
You can continue to work on your interest in dance. Get some inspiration by looking amateur dancer...Sometimes, when I look at videos on amateur pianists, I get a bit of motivation. Also, maybe you can try to be more open to new hobbies? It can also be a chance to realise what other areas you are good at.
Don't give up yet. Good luck.
