In any case, the drain clogged with hair bothers me because it's a reminder of the sorry state my mental health is in, and that despite my best efforts (whatever those are worth), I'm decisively losing any fight I try to put up. The whole process is very stressful. This is one of more apparent symptoms.
I do appreciate the concern, though. You just might want to save it for someone more deserving next time.
Hey. Don't want to misunderstand you or overstep any bounds, but I'mma pull out my soapbox. I'd encourage you to generally cut the "I Don't Deserve Your Concern/Help" stuff.
I recall you're going through trouble with University right now, and it sounded like trouble with motivation. Maybe depression, in general? There were times, in the worst parts of my depression, where I couldn't do anything. I had to count "I took a shower today, ate enough food, and called that person back" as my successes. But they're successes; steps taken in the direction I wanted to go, however small. I would be able to do more later, but for now, I should remember that what I could manage was still good. One foot in front of the other, at whatever pace I could manage.
If you're upset at not being able to do things, or failing to meet an expectation you or others have for you, or whatever... don't be a dick to yourself, or tear yourself down. Be in your own corner, and build yourself up toward meeting those expectations. Or take some time to revisit your expectations, maybe see if they're feasible, or things you want to do, etc. Maybe try something new, or make a different plan to get where you want to be next time. Always keep it constructive, positive, and self-supportive, when you can.
Don't drown everything in the bad. Value yourself. Take some time to dwell on the positives, the growth, the successes, the steps you've taken in good directions. All that.
P.S. It's crappy to yourself to push away other people's concern or help, as though you somehow don't deserve it, It's also crappy to them to feel rejected or unwelcome. Let other people (me, et al.) determine whether they want to offer time or energy or help or whatever they want to offer you! Respect them enough to let them have concern for you, try to help, etc. And respect yourself enough to accept that help.
Also, good luck with all this. It will get better.
