Depressed and pregnant

Carmen
I am 11 weeks pregnant right now with baby #3 and I found out at 6 weeks. This was totally not planned and took me by surprise because my youngest is only a one year old. I instantly started feeling extreme fatigue witch I chalked up to being pregnant, but soon started feeling like this is not normal. I feel like I don't have the energy or motivation to do anything at all. I don't want to cook, clean, get myself fixed up, nothing. I barely feel like dealing with my kids. I have had very pathetic thoughts like I am worthless, and I am a big fat loser. I am slightly gaining some energy but not much. My husband is no help either. He always says that he doesn't know how to help me and that he is the provider not a psychiatrist. I feel bad for my kids because I am not usually like this. I usually wake up and start moving doing chores and activities with the kids. I usually hate day naps. Now all I do is have a hard time getting up and then start napping after breakfast. We have barely done anything fun for the summer. Sometimes I just cry and cry. Anyone else feeling depressed while pregnant? If so how are you dealing with it?
