Didn't you sleep?

I was not able to sleep due to mental state ( little depressed). what to do ? Continuous unsleeply nights making me a unhealthy person and which in turn making more depressed 🥲 and unmotivated. I was not able Sleep due to overthinking.I am tired and my body wanna sleep but my brain is in a loop of overthinking I am depressed due to my current situation.I had a accident and lost my job 3 months ago and had one knee surgery. Also some kind of small small setbacks also happened like health issues and accident falls , breakup s and it's feel like life is not giving me a chance to be free and climb the mountain of success.I was working on my skills .now I am not getting any interviews and it's making me depressed and unmotivated and sleepless nights due to overthinking
