Early antenatal depression or hormones?

Laura
This is my third pregnancy, second child. I am 5wks 2 days. I have felt so irritable, anxious, and alone. I have mild anxiety troubles for years, nothing I really was prescribed daily medication for, just as needed. I am constantly crying, I feel like I hate everything, even myself. I'm even wondering why I wanted a second child, I feel guilty towards my 3.5 year old. I don't know why I'm even typing this on here, I don't have a lot of friends I talk to....and my mom passed away 3 years ago. I just don't have a support system and I feel alone in this. Any one else feel this way? I don't know if it's from my flux of hormones or if it's depression setting in. I had post partum with my daughter, my mom died when she was four months old...so that tipped me over the edge. I was prescribed Prozac daily and Klonipin 0.25mg prn. Just trying to not feel so alone in this....my husband (of 6 years) works long hours and I'm home alone a lot.
