I Want to Do Something Specific But Am Afraid to Try

I want to stop playing any musical instruments especially inside our church and school. Lately, I got a lot of requests. I don't know what to do. I suck in playing, I have stage fright. I intentionally didn't wake up early to be late in our rehearsal for our recording because I just don't feel good at playing piano. I don't know. I just want to quit playing.
