Drugs.

I am by no means a pharmacist, but I believe there are a variety of medications that will temporarily suppress your immediate issue of disturbed sleep so you can get some rest if you need it. Don't worry. Your GP will likely call this option to you attention when you meet. Just know that most sleep meds (that I know of at least) are dangerous if misused or used incorrectly. This in combination with therapy should get you back on your feet.
