I used to struggle really bad with no sleep, it's physically and mentally draining. I went to see one gp who automatically gave me sleeping pills. He made no attempt to find the cause. I wouldn't take the sleeping pills I was too scared too. I went back and seen another doctor but took a list of all my symptoms and worries, she was lovely and really listened to me, she gave me antidepressants and beta blockers and they are helping me. I still get bad nights like tonight, but I don't fight it anymore I just get up and take a blanket downstairs. I either re read a favourite book or watch a silly film until I'm exhausted and fall asleep. I hope you have better look with your gp tomorrow and find something that helps you
