Possible trigger warning..

I'm not sure if this this the right subreddit to be posting in, but does anyone else struggle with racing thoughts at night? I didn't always have them, they started about two years ago. I have suffered from OCD, anxiety, and depression for as long as I can remember. About once a week usually during the evening hours, my mind gets flooded with horrible debilitating thoughts. It's like I have no control over my mind anymore, I just think about random things over and over again. It makes me think I need to go to the hospital and be sedated. Usually when they happen, I toss and turn in my bed, sobbing uncontrollably. It feels like I'm going insane. The only thing that helps me get rid of them is falling asleep. The next morning when I wake up they are gone. I was wondering if anyone had any advice for when this happens, or just knowing that I'm not alone would help a lot. It's the worst feeling and I would not wish it on my worst enemy.
