Don't think your abnormal
Guys probably aren't experiencing parenting the same way. For one thing, the baby is produced from you, by you, and if you are breastfeeding then you are also the sole source of food for the baby meaning you are physically creating the food and must be present day or night to feed the baby. It's exhausting. On top of all that it's likely the mom who will end up with big gaps in the resume, who will most likely be the one to work part time or take on less work outside of the home while being expected to pick up all the domestic tasks. This can mean a big disruption in how you identify yourself, in how you will achieve life goals, in the relationship you have with your husband, your pre-existing friendships etc. See if you can get help, sometimes even a walk in clinic might be the answer if you need a medical referral. Go to community centres, go to parks, meet other moms. I'm not sure how it worked but I think as a community service, I was grouped together with a bunch of other moms who had also just given birth. We didn't all have a lot in common but it was a social outlet, and we could all share experiences with each other. I did not have any family with babies, and no friends with babies. My midwife was a lifesaver as well, a good source of realistic information and an adult human to talk to. I know somebody told me about a post partum depression group at a local hospital I could go to, I was so exhausted after my son was born I was hallucinating. When my son was a year old, I met another mom at a public library program whom I became very close to, like a second family. You really need to build a little safety net, a little community. Post partum depression is very real, take care of yourself.
