Anyone?

Hello- so my intrusive thoughts came back and i upped my lexapro from 5mg to 20mg. Now for 2 weeks. Still don’t feel great. Anyone know if it takes longer to get back in your system? Or what? Frustrated . Txs

These past few days I was fine. Minimal intrusive thoughts ,no anxiety etc(to add I'm on medication so maybe it's starting to work although it barely is 2 weeks) and today I got a sudden wave of anxiety and it started latching on some thoughts like" what if I'm in denial and I wanna break up with my bf? And what if erp doesn't work for me because I actually wanna break up with my bf?" But they didn't really stay long usually those thoughts would make me spiral for days or so, now they lasted for some hours. And now I'm trying to trigger myself into being anxious again because if I don't it means I don't have ocd and if I don't have ocd it means I don't love my bf and if I don't love my bf it means I have to break up. Idk if it makes sense but the lack of anxiety makes me wonder if I actually have ocd or not.

can anyone give me some insight on this? i was given 20 mg of prozac by my doctor to help me calm down while i wait for a psychiatrist appointment for ocd (i went in for an ekg because i was worried. nothing was wrong) yesterday was the 2nd dose, should i expect anything? i almost feel like it keeps me up at night since i take it around 7 pm, and i already have been sleeping poorly for a week or so.
