Emotional wreck

Here lately I’ve been having such emotional highs and lows. I’ve dealt with postpartum depression after my last to pregnancies. My daughter is about to be a year old and it’s like it’s just getting worse. I feel like I constantly picking fights with my S/O. I don’t want to push him away but I feel like that’s what I am doing. One day my anxiety is at an all time high and then there are days where I don’t even want to leave my bed. I just want to pull the covers over my head and sleep all day. How or what can I do to help? I want to do anything in my power to try and deal with this before I speak a physician’s help or choose the medicine route?
