I think everyone here can relate to how you are feeling. I know that the change in weather is murder to me, and since I had to cut back on my sleep meds, I know what it is like to not get much sleep. It is hard, and it does impact your everyday life.
I am currently looking into Ashworth College. I want to get a degree in writing children's books. The great thing about online colleges that are accredited is that you can work at your own pace. You don't have to worry about deadlines, or going out to sit in an uncomfortable classroom.
There are a lot of ways to work at home, and if you feel fulfilled when you are in school trying to better yourself, I would definately look into online colleges. Ashworth has a lot of interesting degrees. A lot of them, I am sure, you could find a job with to work at home. I would love to find a job that I could do from home.
I wish you the best of luck.
