Hello, do not feel stupid! We have all mad choices that when looking back it's easy to think differently. Please stay strong for your littles ones sake. Being a male I cannot give you advice on the pregnacy things. However I am a working father of two. One child is from my girlfriends previuos marriage. I love him to death.
I do know about working alot too! You would'nt believe the amout of hours put in on a normal week for me. Anyway, try your best to take care of yourself!

Good luck!

Hi,
i really hope things have gotten better for you. God has specific plans for your life and although right now that seems impossible, he does. He knows whats best for you. That sounds like nonsense I know, but it is very true. Could there be a hidden blessing in this? Are you too busy focusing on the bad to see anything positive in this? Were the fathers no good in ways that could have brought you or your daughter or the new baby down? Think of the good that is happening even if it is just seeing your daughter smile each day or feeling your baby kick.
Start a journal while you are on bedrest. One day you will be a successful mother and if you read back on difficult times like these, you will say aha! So that was one of the reasons god had me face such stress or sadness or maybe you won't have an aha moment, but you will see you got through it and you stayed strong for your children. Maybe this is one of the missions god sent you here for. We never really know for sure, but I also suggest prayer. Ask god to open your eyes and heart to blessings around you.
And you are not dumb!! These children are gifts and are to be here for a reason and just think, god chose you as their mother. What a compliment.
Good luck and god bless.
