2nd trimester

Feeling quite sick this last week, kinda feels like a cold coming on, I feel the worst in the morning. I feel very uncomfortable in my abdo area, and have pains that dr knows about. Also very very tired and feeling quite breathless when I do anything..(I'm only 16 weeks). Just generally feeling disgusting and overly emotional (to the point of being ridiculous). I had a complete mental breakdown in January and very shortly after found out I am pregnant. I have further since found out my baby had a genetic condition (of which I lost a brother to). I have depression too, have had for the majority of my life.  So this pregnancy hasn't been easy. It's been one thing after the other. Scared for the future.
