I dont even know whats real or not anymore

I used to be able to determine what was my OCD and what’s real life but now it’s all just blending together. I literally can’t tell what’s true between what’s not true. my overthinking is absolutely terrible and rituals and everything is just crumbling.

Why does ocd make you feel uncertain about everything. Even the things you knew were 100% certain before. Its so bizarre. All the subtypes like Rocd, Pocd, Hocd you should be 100% certain about these things but ocd makes you feel like you dont know. I sit here know saying in my head I DONT KNOW. its so hard and confusing. I just want to know who I am. Am I a good person like I thought I was and have been my whole life or am I someone else. I just dont know. Its awful

can a false memory feel very very very real? because i literally don’t know if something happened or not. absolutely no clue but it feels so real
