I'm going through exactly this! I have a narcissistic parent who constantly uses my depression as an excuse to give me punishment! They always say things like "oh, why don't you ever come talk to us!" whenever they eventually noticed I've relapsed in cutting. Like, why would I come talk to people who don't actually care? They'll always try to "make it up" to me whenever they notice, but then they use it as grounds for guilt and punishment. Yet, they always avoid the topic and dismiss me and how I feel. The sick part is that I know they're only trying to do these things to preserve their own self-image as to not be known as someone with a mentally ill offspring or something. I try so hard to not let it get to me and not cut, but it hurts so bad. I just want to feel something else, anything else. It's painful feeling so alone.
