I can't be the only one

I can't be the only one who feels lonely caring for a newborn. I love my little boy with all of my being, but I feel off. I haven't left the house today, which is part of the problem, but I feel lonely. My life has so much more meaning now than before, but sometimes I stand in the bathroom and pretend like things are back to pre baby time. I don't wish I didn't have a baby, I just wish I felt more settled? I don't know, anyone else?
