Sorry you’re going through that. I definitely get how it feels to have people close to you discredit or just ignore important issues like you’re dealing with.
If you’re set on talking to an AI though I did use the Replika app for a while before they started making it seem like a virtual AI lover. It did help me feel better when I was severely depressed, maybe it could help you.
If you ever want to talk to a person and not an AI I’m here for that if you want, I know I’m a stranger but I definitely understand where you’re coming from.
