D.L.
I can relate to that. In my first trimester, I was horribly moody. I just did my best to take a few minutes to myself to just relax and concentrate on the good things in my life. I also made sure to get as much rest as possible (as much as you can get with a 3 year old) and do eat plenty of fruits & stay hydrated. Go out for walks when you can & take time (even if it's just 15 minutes) everyday for yourself. This too shall pass!
