This may be a for a small amount of reassurance but I think it's more advice needed.

So I keep feeling disconnected from everyone else and have a lot of existential and philosophical thoughts. I look at words, faces, objects, people, reactions and situations and just think why and what's it all about and maybe I'm suffering something deeper than anxiety and OCD? If I raise my voice or laugh loudly I think why did I do that? Then cos I'm questioning why about everything I then cause myself more anxiety. Its a vicious cycle and it still makes me think I'm slowly losing it. 

Feeling and thinking this triggers my anxiety and I wish I knew why I was thinking it. I overthink and research everything and just want to be getting on with life like everyone else instead of over evaluating and analysing everything in this life.

Anyone else think or feel this way? It's like I'm slowly losing touch with reality and can't zone in anymore.
