I miss my previous life

My baby is two weeks and I can't stop thinking about my previous life. I really enjoyed where I was before giving birth. Loved my pregnancy, as I got to travel, walk, and read a handful of books. I really enjoy reading and I've tried to take some time to do that in between baby's naps but I can't seem to concentrate anymore. I also crave freedom. Meaning the possibility to do whatever I like with my time, which I now cannot anymore. I hear other new parents saying their life has a new meaning since the baby but cannot relate. All of this is too exhausting. You completely lose sense of time and sense of self.
