Agreed.
Unlike some other Chazzers here, nobody knows Barbara in person... all we have is her posts here. And she hasn't been here very long either so it's not like we have a long track record of getting to know her. I think it's a little premature to make major judgements on how she will be as a parent.
I also think saying "I wish my mom had killed herself" and "Barbara reminds me of my mother" is incredibly INCREDIBLY damaging to say to anyone, but especially to somebody who is obviously in a bad place right now.
I do 100% agree that Barbara needs additional help here and I hope, Barbara, that you remain in touch with a therapist. I hope your OB/GYN is being helpful as well. And I think it's wise to search out a good pro bono lawyer to help you too. There are so many people out there who can help you. You're not alone, and even though I know you have gotten some harsh responses here, many of them come from a place of wanting to help you get out of a bad situation rather than hurt you. Tough love is one approach to dealing with people - not always the correct one but it is how some people function.
I have lots more to say but really it just comes down to you clearly need support, and I hope rather than shut yourself off, you seek it out. Because the support is there for you. It's here for you too if you want it.
