I'm so confused

Kimica

Im 7mos pregnant. I have several disabilities along with bipolar and severe depression. Im married and have no one to talk to. My husband tries to understand but can't and my family never wanted me as part of the family since I was born ( im 31 going 32 soon). When I had my first son I couldn't stand him myself or his father. I wanted to cut my son out and kill myself. Some how I was able to get through the pregnancy without doing harm to me or my son. My daughter, for whatever reason no problem!!!. Im pregnant again with a boy and im going through what I went through with my oldest son. I tell my doctor these things and says there's nothing to worry about!! How is that when im having suicidal and homicidal thoughts. I have these from time to time but my pregnancy amplifies these thoughts. I need to do something or I'm going to be in bad shape. Im asking to have him earlier so I can get back on my meds. What should I do? All I can do is cry and I feel im being tortured!! I need help, anyone?
