TL;DR 
My anxiety thinks the sun going down will kill me. Now I can’t sleep. Can anyone suggest a potential fix?

A bit of backstory. I (21F) have had anxiety ever since I was a little kid, but I was officially diagnosed and prescribed medication my freshman year of high school. 

The thing about my anxiety is I don’t actually stress about anything, I will just be going about my business and be hit with a panic/anxiety attack out of nowhere. I forget what my psychiatrist said it was called, but basically I just HAVE the chemical imbalance, not the thought patterns causing the chemical imbalance. 

My doctor and I recently decided that since I’m older, I might have grown out of the imbalance. We decided to try come off the medication in order to help me lose weight, since the medication I’m on can make it hard to lose weight, and no amount of dieting has helped much.
I feel like the medication is finally fully out of my system a month or 2 later, and I’m miserable. 

What’s weird is I’m totally fine throughout the day, but the second the sun starts to go down, my body just decides to panic. I avoid anything the could possibly be a stressor, horror movies, scary stories, etc (all things I really enjoy when I’m medicated or during the day). But for whatever reason, whenever  the sun goes down, my body just decides to feel like the dark will kill me. 

I’m walking around from about 7pm til Midnight in a constant mild panic. Rapid heart rate, flushed face, shakes, etc. and when I finally try to settle into bed at about 2am, I just toss and turn for hours. Some nights I’ve only gotten about a half hour of sleep before I have to get up. I’ve resorted napping durning the day since my body won’t let me sleep at night. (Before you say it, I know it can make it harder to sleep at night, but even when I’ve gone a few days without napping I still can’t sleep).

Does anyone else have this problem? If there anything you’d recommend? As of a few days ago, I’m trying CBD isolate gummies at night, but I’m either  not taking the right mg or it doesn’t work for me. Are there any other suggestions? 

I don’t want to go back on the meds, at least until I’ve lost about 40lbs, but I will choose my mental health over a number on the scale any day. I just want to try out all my options before I go back. Any suggestion is appreciated.
