Scared I have postpartum depression

I love my son (9 months old) and when he was first born it was the happiest point of my life. However now, with him being able to walk and grab stuff, it seems like all my life consists of is working, coming home to a messy house with a high maintenance child, sleeping half as much as I work and eating half as much as I used to. I feel like the life is being drained out of me and it’s making me struggle to not only bond with my son but also everyone around me. How can I just get over this and continue working through it?
