you need sleep first and foremost before you do anything else.
If you can't manage good sleep and plenty of it don't go to the doctor unless you want to be prescribed something specifically for that because in my experience that is going to be their first step. I went in for a few symptoms that could have been neurological the first thing every doctor did when they heard I work nights also is stop writing notes and then explain to me how I need a proper sleep schedule ... Turns out I had cancer but yeah sleep was their first goal. It throws everything out of wack.
Get some sleep however you can and see if that helps. Get restful sleep and then if you are still having issues you can go from there.
