Hi Ken,
My advice would be to try to focus as much as possible on something you love – music. I know, you feel let down by not being able to enroll for now, but don’t give up on your dream. The more time and energy you spend on doing what you love, the less time you feel depressed. It gives you a sense of purpose and it energizes you. I know it’s easier said than done, but you can treat music as your lifeline – this one thing that keeps you afloat, that is stable, always there for you, and never betrays you. If one way doesn’t work out, find another, but do not give up. Also, notice, how different kinds of music make you feel. Music can be very powerful in evoking lots of emotions, choose the kind of music that makes you feel good or just a little better when you feel down.
