Desperate for sleep

It has been months. I cannot go without anymore. I can not. It is affecting my mental health and health in general. I may get 6 hours one night a week. Nothing that I have been prescribed will work. Trazadone is candy, mertazipine, seroquel, hell- Ambien, Belsomra, Lunesta. Nothing. I wander around all night drunk. It just doesn't work. I want it to but it doesn't. And I am in Knoxville TN. Here, the dea are sons of bitches who keep the doctors scared to prescribe anything else. The only thing that I have taken that works is valium and nobody prescribes that anymore. I am at my wits end. Any advice would be appreciated.

***EDIT- I have found a place that has both a licensed Psychologist and Psychiatrist that work together. It is expensive, but I found a way to pay for at least 2 visits. The appointment isn't until mid-February, but the appointment is set. And that will give me time to figure out how to continue, if it is beneficial.

Thank you ALL for your good advice and input. It helps to know that people care and that complete strangers were willing to take the time to read and offer their insights. I read every reply and I will try everything that worked for you all. Even if I have tried it before. Again, thank you all.
