When I was younger I used to have intrusive thoughts that was completely erratic and entirely out of my control, I'm unsure if this has anything to do with schizophrenia.

I also used to have OCD that completely ruined my childhood as well as anxiety about ridiculous things.

Today I feel as thought I have a control over my OCD however sometimes I feel like I'm relapsing and I have to kind of fight with myself to regain control of it.

Sometimes I find myself pretending to have a conversation with someone even tho I'm the only one in the room, almost as if I'm creating a fake scenario without realising I'm doing It, is this possibly a symptom of schizophrenia?

The more and more I think about it, the more I feel as though I'm not entirely normal mentally. Sometimes I doubt my sanity and my mental health.

Normally I just kind of kick this shit under the rug and don't talk about it, but to be honest I'm depressed and I don't think I can speak to anyone about it. 

I'm lost as to what I should do about it.

Thanks for any help.
