I have 8 month old twins, stopped pumping by 2 months and still do not think my hormones or emotions are right.
Birth Control - I have been on birth control for 4 or 5 months, though I had a period every other week for the first 3 months with that. My OB changed my BC after 2 months or that and now if I take a pill late on any given day, my flow starts coming. My advice related is to talk with your OB's office about your hormones and feelings as I understand so much of your feelings is effected/driven by your hormones.
Anxiety/Depression - I know that I have struggled with this since my kids have been born. There has definitely been a lot of worry out of love for my kids that has contributed to this. I keep getting disappointed in people that I thought I should be relying on during this time and now that I know I need support of others, I realize how non-existent support has been for myself for a long time. My advice related is to be sure that you are taking care of yourself, don't be afraid to ask for help, and build a support group - if you do not already have one.
Hope you continue to have much joy with your little one.
