Stop it! You're doing the best you can so there's nothing wrong with you; nobody does it better
People making back-handed compliments have the problem, not you for being hurt! If you wander over other people's boundaries, they're responsible for telling you! You can't be a bad person if you're trying. That you care says you're a caring person! Bad people don't care. Remember that logic, it actually made sense.
Sorry you're hurting from today. Tomorrow's Saturday, no classes?
