From what I'm reading, you're a young man. Right? College aged? Dude, you can't contemplate ending something you really haven't started yet. (i.e. your life) You have no idea how many wonderful things (and yes, a few lousy things) wait for you out there and if you decided to jump ship now, you will NEVER know.
Cut yourself some slack, look further ahead in your life than the next week, month or even year and trust that you're here for a reason. To cut the trip short is irresponsible and hurtful to everyone who knows and cares about you.
Now, go pick up that axe and play! There is no better salve for a wounded heart than to tap into the great flow of creative juices that is cruising around the universe. And don't let any of the Great Blues Masters hear you say that pain, sadness and depression does not make for some killer music!!!!
