How do I stop feeling shame for intrusive thoughts?

I suffer from intrusive OCD thoughts it keeps on tormenting me and giving me anxiety. Every time I try to not pay attention to them there is like a Demon whispering in my ear telling me I'm a awful person and I don't deserve to live. It's haunting me almost everyday. Matter a fact, RIGHT NOW when I'm typing this I'm feeling anxiety "why are you trying to get help? You don't deserve it." It's echoing in my mind right now. PLEASE someone give some advice to stop this.
