It's so hard to tell the difference between reality and ocd, for thoughts and feelings. I'm just always confused.

Difficult To Distinguish Between Real And Intrusive Thoughts

"Pure" OCD

Suicidal OCD

I get this so much I always end up looking at something for a long time living in my head then I look at something and realize it’s reality so was I in my head the whole time? I don’t know it stresses me out so much it’s probably different for you but your not alone! I’m so scared all the time 

this sounds a lot like you're ruminating on your thoughts.  OCD will keep coming back up if you keep trying to find answers between whats real and whats ocd.  what if you learned to accept that MAYBE its all the same?  what would be the worst case if you didn't give it answers?
