Around midnight I start having paranoia and anxiety is it because I’m sleepy and how can I calm myself?

I always had trouble with anxiety. I never learned how to control my anxiety attacks and calm myself down. A couple years back I was diagnosed with depression and anxiety disorder. About a year ago I was feeling pretty good and with my psychiatrist’s approval I stopped taking my medication and stopped going to see her altogether (because my parents were so desperate for me to be “normal” again and not dependent on therapy) These past months I started to struggle with my mental health again. My sleep schedule is not doing so good as well. Usually I would go to bed around 11pm-12am now it’s more like 3am-4am. After midnight I started to have constant paranoia like I feel like something’s going to burst out of my door and attack me and I keep imagining senarios about me being attacked and seeing creepy smiles and stuff. For hours after midnight I constantly feel anxious and in a flight or fight mode. Those this happen because I’m sleepy because I don’t feel sleepy. (It might also be because I’ve been listening to a lot of true crime podcasts) Also how can I calm myself because it also makes it harder for me to sleep and close my eyes, I feel like if I close my eyes I’m gonna be attacked and caused me insomnia.
