Feel like I am not able to sleep enough

I have a sleep disorder. I have been taking Ambien for a long time. But it has never been a big deal and I would always get enough sleep. A couple months back I felt like no matter how many hours a night I slept I couldn't get enough sleep. It got better, until about the time change. The first day was fine, but every day I just keep getting worse. No matter what time I go to bed, I just want to keep on sleeping and it is hard for me because my older two kids have to get up and get out to school. For example today, last night I went to bed at 7pm and then heard my alarm go off at 6:45 am, and I kept on pushing snooze. Well I got them up at 7:30am and then I went back to bed until about 10:30am. This is not like me at all. But even being up for an hour I wanted to go back to sleep. I feel horrible. When this also started, I started coming up with bruises on my legs that look horrible. I was always easy to bruise and would always wake up with bruises on my legs not know where they came from. Now the bruises are getting bigger and worse. Where even though it is 80 degrees, I can't even wear shorts, because it ooks like I have been beat really bad. These bruises are horrible looking. I just tell people that they are from playing sports with the boys, but no matter what they aren't and they are just popping up and I can feel them starting and see them pop up. A couple weeks ago, I had one on my wrist that looked like someone grabbed me a perfect thumb print, even to reach around and have the imprint of the other finger. Could these go hand in hand? What could be wrong with me?
