Looking for advice

Hi everyone,

I am a 35 y/o mother to a lovely 3 year old girl and I am also 12 weeks pregnant. Since finding out I was pregnant (planned) my excitement quickly turned into fear, panic, screaming episodes, severe depression and suicidal thoughts when thinking about having this baby. I have laid in bed for the past 7 weeks, sleeping all day, barely eating and completely unable to care for my daughter (my husband has had to do everything). I have a history of anxiety, depression and OCD but this pregnancy has literally had devastating consequences on my mental health. With my daughter this never happened during pregnancy. We have been talking about terminating the pregnancy as my husband and family know my mental health history and struggles and don’t want me to get worse over the next 6 months or relapse once the baby is born... in which case having severe post partem means I will be unable to not only care for my older child but the baby as well. They believe I should focus on my mental health and being a mentally sound mom for the daughter I already have as she needs me more than a sibling, I am being treated with antidepressants and finally today, after 5 weeks, I’m starting to feel less weepy and a bit more relaxed which I expect will only get better..,although still not excited about the pregnancy. My question is if prenatal anxiety and depression have been so severe you were unable to function and meds helped a bit but you were at risk of having severe post partem would you continue with the pregnancy? I am also seeing a therapist and for those that may be wondering why I waited this long..,I wanted to see if the meds would totally help before I made any decisions. Please let me know your thoughts.
