Simple Solution:
FUCK IT!
If your not injoying where you are in life, then Fuck it and move on. There are thousands of diffrent jobs out there, you just have to find one that you enjoy. Go back to school, do another degree, search the papers, ask your mates if theres other jobs out there.
If your not happy with your life then you can either quite (death is easy) or change (which can be fun).
