I don't really feel anything. Is this normal?

I feel like I'm. Not me anymore. I've tried saying whatever i don't care but I don't know what I'm feeling now. It all brought so much anxiety at the start and now it's complete numbness I don't feel attraction towards anyone. I want to towards my boyfriend. I feel like I'm a shell. I don't care what happens anymore. I still don't think I'm lesbian but my mind is so convincing. I have been bombarded with intrusive thoughts, images, memories and feelings and now I don't know what to believe. I feel really ill. I haven't had a period in 2 months because of stress. I'm starting to give up. Is this normal? I feel like nothing will help.
