Post partum phase. Male relationship.

I am having bouts of anger and irritation specially after delivery.. Generally I am happy and blessed but at times I get hyped up with anger. I am annoyed most of the time with everything around me. I love my baby, husband and family. Sometimes I feel like my life is ended.. My career has stopped. I have no friends. I am alone. I am single child of single working woman. I had felt loneliness from my childhood. We both are teachers. She is the best mom and friend. But I feel I should have a sibling. For my 3 month old daughter I want a brother/sister. But I am so much irritated, fed up by my husband. Even though he does all he could. I feel jealous of him that he is not having any pain, stress, his life is not altered. I had a c section as advised by my gynae. I am exclusively breastfeeding my child that also bothers me at time. I am weak at relationship with male... As my father left us.. I always feel insecure with every male relationship.
