Hi there,
I'm sorry you're going through this. I'm here actually because my husband is dealing with antenatal depression (I'm 8 months pregnant) and I'm looking for ways that I can be of help to him.
The one thing I can say to you is PLEASE be gentle with yourself. You're doing a great job at being a mom and wife. Just the fact that you're feeling guilty tells me that you always do whatever you can for your family. Maybe just cuddling with your daughter while you both watch TV together can help you feel like you aren't losing the time with her, or feel guilty about the TV time. Your body is going through a lot right now and so is your mind, so give yourself the okay to let it go for a little bit..
When it comes to your husband (speaking as the wife of someone going through what you are...), pick something... even if its ONE thing.. ask him to help you with it. Pick something that he can take off your plate if you're feeling overwhelmed.... pick cuddling with him in silence for 10 minutes everyday if you're feeling distant or unconnected with him... ask him to tell you one thing each day for a week of why he fell in love with you...I would love for my husband to reach out to me and tell me how I can help.
Anyway. I hope this gave you an idea or two. If they let you know of an antenatal depression forum, let me know!
