if you don't like where you are, but are bound by some form of obligation left unmentioned, re-invent your perspective.Choose to feel good, find the strength to explore new options, make new friends etc. Or maybe you need to reflect on where your priorities are at. What are you obligated to, is it something that you have a choice over, does it do you any good, do you need to re-claim your own life?
I agree with Widerstand about camping. Cities are all in all, an unhealthy environment for humans and non-humans alike to spend all their time in. Spend a couple weeks living in the forest, eating healthy food, moderating your consumption of intoxicants (because even pot and alcohol really bring down your mind's ability to function effectively), turning off the video games etc.
