My friends dont care about me.

I've been posting about being super depressed for 2 months now and I just want the people who I care about so so much to say something. Anything. No one asks if I'm ok. My own family won't even help me. Idk what to do. I'm thinking of deleting insta, tiktok, and twitter. I want to disappear. I want to go ghost and make it seem like I was never there. The urge to isolate myself is growing more every day. I already deleted my private insta and accounts on every platform that I don't use anymore. People I've been friends with for years see my posts and my pleas but no one answers. I feel so alone and angry. They tell me "Hey if you need someone to talk to I'm here" but when I make it known that I need to speak to someone they all ignore me. Fake friends. No one truly cares. I have to go through this without them. Maybe thats for the best. The guy that I've known since I was 4 years old sees me talking about taking my life and says nothing to his or my parents. The girl that I helped get through HELL won't offer me a hand. She didn't even invite me to her birthday party. No one asks me to go out with them, play games with them, watch movies, go to conventions. NOTHING. If I cut all of them off now I'm doing myself a favor.
