Derealization and pregnancy

I have anxiety and depression which I take lexapro for. I have a lot of derealization and some days it’s better and some days it’s worse. I just found out I’m 5 weeks pregnant and it’s okay to continue my lexapro. Has anyone experienced all these things at once. I literally am so anxious doing anything and I get hot and I feel like I can’t participate and normal life because of beings scared of how everything feels. Any suggestions or advice?
