Hi sdav80,
I do have treatment-resistant depression as well. I take Effexor XR 300 mgs/day and Seroquel to pack more of a punch. Combined treatment, I think that's what they call it.
Even still, I am low. I go through very hard times & haven't gotten better than being in a "moderately - severely depressed" state of mind. That's just the way that it is for me. I do exercise regularly (that seems to work best for me), and appreciate nature whenever I can in tough times. I have identified nature as being my happy, "safe" spot. It brings me a sense of peace and tranquility. I therefore remind myself of nature's beauty very often, to get me through.
I do agree with others, that you have stressors which probably do add to your depression. Recognizing that could bring you a small sense of peace. College doesn't last forever. The end will come before you know it ~ and then you'll kind of wish that you could go back into that "safer" environment

! Do see a T, if you aren't doing so already, to help you work through the emotions that you're struggling with.
Best wishes to you!
