I’m tired of not sleeping

When I’m extremely depressed I don’t sleep or eat. I haven’t had a restful night of sleep in months. I went from a waist size of 36 down to a 32 in a short amount of time. I’m tired of not being able to sleep. I was supposed to see a psychiatrist today. But my appointment got canceled and the earliest they could get me in was next Monday. It seriously sucks that I’ve already been waiting for this appointment to come for a month now. And yet it’s been moved again. I know what meds I want as I’ve been on them before. I’m so tired of not being able to sleep. And when I do sleep. All I have is nightmares and when I wake up reality hits me so quick my anxiety comes on so fast. I just want it to all end.
