As far as your job is concerned, maybe you can transition from it into something you really enjoy doing, ie, whatever it is you are pursuing a degree for. In the meantime, are reduced hours a possibility? You could explain to your boss that with you going to school, you need more time to study. Maybe a part-time schedule can reduce the stress you are feeling. Another thing you can consider as far as stress is taking a break. Take some days off and unwind.
Since you re going to college next month, have you thought of looking into living on campus/college housing? You could get a roommate and share the expenses. You might even qualify for a scholarship that would go towards housing. Talk to your financial aid office if you haven t yet. A lot of students opt for on-campus housing, so you wouldn t be the first to have ever lived away from home while studying. This is a good time for you to seek all the help you can get from your Advisor, school counselor, etc. Good luck!
