New Diagnosis

Hello. I am feeling incredibly overwhelmed. I recently saw a new psychiatrist because I moved and could no longer see my old one. I told her about some of my struggles and she mentioned that I may have OCD. I immediately dismissed it because I had a false preconception that OCD is mainly repetitive tasks like hand washing, etc. and didn't entertain the idea. On Monday, I had an appointment with my therapist and I told her what my psychiatrist said. We then discussed it in a little more detail and that's when I realized how much of OCD is in your head. After the appointment Monday PM I could not stop researching OCD. I went down a complete spiral and spent hours looking up symptoms and signs and questioning every event and interaction in my life wondering if it may be OCD. It felt like my whole world was flipped upside down and the floodgates opened. I started remembering things that were likely OCD that I thought was just severe anxiety but now make more sense. Then I started questioning if I am just imagining things now because someone mentioned OCD and my brain is trying to invent symptoms to match what I was reading. I kept looking up more things, reading the same information over and over to "confirm" I had it... and every time I thought I had myself convinced that I do have it - I started questioning it again... this went on for several hours until I was so exhausted I fell asleep. I woke up yesterday morning and it was the first thought in my head. I started replaying past events and wondering if it was OCD related... just questioning my whole life. Nothing felt real anymore. I cried so many times yesterday and I wasn't even sure why. There are so many things that make me feel like I definitely have it but then I just keep thinking maybe I don't? How do I stop? I feel like now that I have this information I don't know what to do with it. I would really love to talk to someone who has been through similar or can ask for advice. I just feel so overwhelmed.
