This Is Ruining My Personal Life And People Just Tell

This is ruining my personal life and people just tell me to sleep. Can you suggest somethingI have worked 6pm to 10am for over 25 years as a nurse. Now that i am disabled my insomnia is even worse . I have been on every medication prescription and over the counter. I use to take halcion .025 2 tabs every nite and this worked great for years, also have taken ambien with good results. Within the past year i had to swirch primary caredrs and immediately i was taken off my sleeping meds. I was given belsomra to trywhich costs over 550.00 a month and did nothing. Tried all the over counter such as melatonin etc
