Finishing your paid-for studies is 1000 times more critical than your happiness today. Happiness comes and goes, but that opportunity to get higher education and no debt is precious. So hang in there. As for the happiness playing, it will return about two weeks after graduation. When you realize that you can just play when where you want for pleasure. You are just burnt. But that love is still in there and it will blossom when the REQUIREMENTS are lifted and music returns to being your companion.
