I would not mention the bp or the postpartum depression, although the postpartum depression is safer because it will go away.
The way I'm reading your email, and maybe I am misinterpreting, but it sounds like your husband is not helping your self-confidence at all! He should be your biggest cheerleader instead of being critical.
What is your outlet? Do you see a t? It sounds like you need to talk this out. Also, it wouldn't hurt for your husband to seek counseling for how to be a better husband!
