It sounds like you know what the cause of this intense stress is. Try to reduce the amount of contact you have with people who stress you out. If you need space for yourself, try to find a place that is comfortable and peaceful; a space were you can relax, reflect, rest, or study for as long as you want or need to. The libraries have plenty of spaces that are conducive to relaxation, study or reflexion. My favorite is the area located at the 4th floor’s north end, where the soft chairs are. You ought to try it!
