Girls are right to reject me. I am completely bat shit crazy. What can I do?

I am weird. I say weird shit. I act weirdly. My perception of myself is completely clouded. I act different every day. I feel like different people. I have a hard time connecting with most people because they think I am crazy. but they are right I am a complete loon. I'm not mad at them the problem is with me. I'm more upset at myself but that is also foolish since I cannot change myself. I have been trying to change myself for several years. but it's a task that is foolish because at my core I cannot change who I am. I am completely crazy with major mental health problems. I feel like it's impossible to find a person to spend my life with. never had a girlfriend. always have done hookups. until the girl realizes I'm a broken human and leaves.
