I'm a fourth year student in Experimental Psychology who is dealing with major, unresolved mental health issues and major problems fulfilling my basic responsibilities. I'm finding myself under-performing this semester big time with late grading, arriving late to classes (first half of the semester anyway), showering every other day, and taking long naps. It has not improved at all and I haven't made any progress even writing for my dissertation at all despite data collection being a thing at the same time. I'm probably going to step down from this position altogether before I strongly anticipate being dropped from my courses for next semester due to my low reviews. How can I broach this to those at the SLAC (Small Liberal Arts College)?
I know I'm also going to invite some backlash but would this do more harm than good (even with the negative reviews on the way)?
