I understand how you feel. I’d ignore people like that and just accept that they have nothing better to do with their life. They just doing that cause they’re bored. But sometimes when I can’t take it I would let them know how I feel and how obnoxious they are and they’d stop. So maybe try doing that, tell them how you feel and how wrong they are. I know that can be hard to do when you’re depressed tho but sometimes you just need to let your anger and frustration out on the person to make them stop. I’ve experienced what you’re going through, it also helps to talk to someone if you’re depressed, someone who understands and it may be hard finding the right person to talk to but try cause the longer you stay depressed the more damage it does for you.
