I cant sleep anymore

Its 5:30 am and I can't sleep again. I have been tossing and turning for the past 2 hours. The worst part is I went to bed at 11:45 pm on prescribed sleep meds. This has been going on for a week now. I am the only one here to take care of our son while my husband is deployed so when he wakes up at 7 I have to be up too. Most nights I only get a couple hours of sleep because out of nowhere I jump up and start shaking bad. I'll go through this 2-3 times a night and can't fall back asleep until I've calmed down. I'm exhausted and in so much pain. I don't know what to do. 😢😢😢😢
