I know what my dream is but for ome reason I can't tell other people

All of my life I have loved music I feel that when i put on my headphones and really listen to the song that is playing its like a way I can express all of my emotion inwardly to myself. It is such a big deal to me it inspires and touches me emotionally every time I play a tune I just get so into it. I really really want to be a signer in life and I know I can do it I just for some stupid reason feel like I can't tell or show anyone like I am to shy or afraid of their response. In effect I have gone to school for something I like while knowing I will never love it as much as I will ever love music. It is very hurtful and emotionally draining when I cannot fulfill and embrace my true passion just because I am afraid of everyone else like f*ck man.
