Can't sleep

Today I wasn't feeling well at all.  My stomach was bothering me all day and I had been up all night.  I've gotten bad about not taking all my medications every day.  One of my medications, Keppra, has some really bad side effects if I don't take my Lexapro.  The Keppra causes depression, but it also causes me to be very hostile and short-tempered.  I know I've got to start taking it again because I've been feeling somewhat down, but also very short-tempered.  I've been out of work and because of that I keep very strange hours.  There are times that I will stay up all night and lack of sleep isn't good for me either.  Hopefully I willstart to get tired and fall asleep and tomorrow will be a better day!!  I need to start exercising again because when I started a few months ago, I started to feel better and I was able to go to sleep at a better time.  It gets me aggravated all of the effects that my medical condition and my medicine have on me.  I have a very hard time losing weight and I've gained quite a bit because of when I was on Disability.  I wasn't able to drive, so all I did was sit at home except on the weekends when I would visit with my family.  Because of that my metabolism slowed way down, so I know that that also is making hard to lose weight.  I may also have a thyroid issue.  That's something that I need to get to the doctor about, and hopefully I will soon.  Hopefully I will start to get tired and fall asleep and tomorrow will be a better day!
