Emotional Pregnancy

I can't tell if I'm more emotional with this pregnancy because it's a girl or because I already have a child to take care of which prevents me from getting as much sleep as last time.
I'm fighting a bad head cold right now and am refusing to take any meds. I took Tylenol last pg but have read studies linking it to asthma. When I have a headache now, I drink caffeine. Last night was bad. I just wanted to cry about my health, my self-image, my lack of energy... Everything! I had a 5 minute cry session in the bathroom before going to bed. Once in bed, I started getting painful contractions on one side of my uterus. I tried to clear my mind, drank water, and switch positions. I eventually fell asleep with the help of my husband rubbing my back.

He's been nothing but helpful this entire pregnancy. In every aspect where I fail to handle my responsibilities, he picks up my slack. On days where I do nothing but slack, he handles housework, watching our son, taking care of me, and taking care of himself. I don't know where he finds the strength to do it everyday, but I know how lucky I am to have him. I'm now 33 weeks pregnant, so I know it's going to get worse before it gets better.

My personal goal is to try and de-stress as much as possible. I can't pinpoint the cause of my emotions, but I certainly know their effects. I don't want preterm labor, and I don't want my hormones somehow permanently damaging my daughter. I'm going to work on getting more nutrients in my system, drinking more water, and getting more sleep.
