6 weeks and with bipolar mainly depression

Hey ladies!!!! I am wondering if anyone of you have bipolar. I was diagnosed 2006. This is my second pregnancy. My first one was a stillbirth last year July 2014. I am feeling scared and nervous about this pregnancy. I get really depressed to the point that I don't wanna eat anything and do anything for myself. So I ask myself if I can't take care of myself how can I take care of a baby? I know it's doubts but I do believe I can be a good mother but sometimes I feel like my depression controls me making me feel hopeless and useless. I am grateful to God for this second chance. I am taking lamictal and Wellbutrin. I am wondering if any of you know about these medications?
