Hmmm....I guess I don't see anything too horrible with your life. You have a job and aren't in debt, not a lot of people can say that. I do understand the rut part I guess. I was there. I actually moved to Duluth, MN but now I too am in St Paul. Small world. Its smart that you are considering further education, nothing wrong with thinking of the future. I would maybe talk to a career counselor at your school and see if they have any career path advice for you.
Do you have health insurance? Maybe consider seeing a doctor about the need self medications. I too have been there. Its easy to become depressed when you feel like you are neither going forward nor moving backwards.
Sometimes you just have to bust out of your comfort zone. Do you have friends or family in a different location that you could maybe temporarily live with, just for a change of pace? It might be good for you to get away and experience some new territory for awhile. Meet new people, explore who you would like to become.
So, so you think you can tell Heaven from Hell,
blue skies from pain.
Can you tell a green field from a cold steel rail?
A smile from a veil?
Do you think you can tell?
And did they get you to trade your heroes for ghosts?
Hot ashes for trees?
Hot air for a cool breeze?
Cold comfort for change?
And did you exchange a walk on part in the war for a lead role in a cage?
