Maybe it's not that they don't care. Maybe they don't understand? I feel the same way though. I haven't told anyone that I have suicidal ideation, but I try so hard to explain what it feels like for me to have brain fog. I feel like they just don't understand, and they think that I'm "just being myself again". Meanwhile, I'm telling them because I don't feel like myself. Where the brain fog is concerned, I want someone to tell me that it's going to be okay. Even if I know it won't be. I want someone to be genuine and want to try and understand me. To try and help me and not expect me to do things alone. I'm not a needy person, I just want people to understand.
Have you tried sitting down and being as serious as you possibly can with them? Maybe they need to know that you're being dead ass serious. I'm sorry that you feel this way ❤ I understand your frustration, even if it's different for both of us :/
