It is hard to offer anything more than general thoughts, given that I feel like I don't understand much about your situation or what the real challenges are (not telling you that you have to share more, share what and when you are comfortable, but it may impact how well people can offer advice) but if boredom and is an issue, maybe consider taking up a hobby. Learning an instrument is a healthy outlet, and guitars are not too expensive and portable. Exercising is another healthy activity that can be done just about anywhere. If you want any subjects you would be interested in learning about, (or want to work towards a GED if necessary, or prepare for college etc.) there are free online resources for many subjects including Khan Academy (which has short lessons on everything from 1+1 to vector calculus (or something like that.) Websites like coursera offer free college level courses in many subjects and may be a way to learn some things that will help you be able to make a Parnassa in a field that is more of interest. There are many computer programming courses as well.
Hatzlacha!
