Pregnancy + Divorce + Stress = Mentally exhausted

The moment is almost here!! I'm currently 36.5 weeks pregnant, Marin is pretty much due anytime now. Her suggested due date is Feb 17th, but my doctor says to really expect her at any time since my body is already showing signs of "tiring out" as I call it lol. There were only 3 months between my pregnancies, and that doesn't really leave adequate time to heal properly. I definitely feel that way anyways. I go tomorrow to schedule the c-section, unless she decides to come before that date. Since Connor got stuck when I tried to deliver him naturally, and had to do emergency surgery to get him out, I just opted for a c-section this time around to be on the safe side.
I am nervous however, now that my husband and I are separated (since July when he moved in with his girlfriend) on how the hospital stay is going to go. I know my baby is in good hands with the doctors and nurse team - I'm worried about the after part. He knows its still hard for me to except the fact that he left, but he's shown numerous times he doesn't care about it -- Mentions her every phone call, brings her to all the visitation pick up/drop offs, even bringing her to my work and home when I've asked him countless times not to on at least that one.. So I'm afraid he's going to bring her to the hospital. But I'm also afraid that if it comes down to it, and he sees for real that I will not let her up there that he will just turn around and go home and not see his daughters birth. I've got 2 weeks to try to get this straightened out.. or at least partly... cause when it comes down to the day I guess he's still gonna do whatever it is he wants to do. He's always been that way, his way or the highway.

I'm also stressing over the breastfeeding, I barely produced enough for Connor when we were together (only produced for a month and a half), now I'm going to have to somehow try to pump enough for regular feedings plus extra because of sending her with him for visitation away from me for a whole day. Can you imagine the nipple confusion issue alone with that! TMI I know I'm sorry. But this sH!t is hard to workout in my head, and my hormones are NOT helping lol.
I just pray that the good Lord will provide both my babies with everything they need to be happy and healthy through this whole new stage and drama in their lives. Divorce is hard, and can be really difficult on babies. Sleep/nap schedules getting thrown off from visitations, diets getting thrown off, and even attention/learning times getting thrown off. I also pray that I can give them as much security, love, and time as I possibly can to insure that they grow up to be respectful, successful and happy adults.
