Can't sleep, I can't take it anymore!

My head feels like its going to explode, I been up all day and now going into the next day morning, it's now 330am. Ive taken a warm shower, drank some water, read, I have a small fan on me, plus AC. I taken care of all my emails, I can't do this anymore. I'm starting to have bad anxiety due to lack of sleep. This has been going on for a few weeks now, off and on. Seeing the Dr tomorrow morning, I mean today in 7 hours. 😨😨😖😖😭😭
