Feeling ill still 4mo postpartum

Hey ladies, so for the past month I have physically felt like crap. My legs ache horribly all the time, my stomach is constantly sour and upset, many days I have little to no appetite, now I am getting little headaches too. I am on medicine for PPD and the pill birth control and the last two days I have had some spotting so I suppose my period is returning. When I talk to my doctors about the physical symptoms they say PPD can cause all these issues but I feel like crap!! Has anyone gone through this or is and can say it improves. Im sure hormones are a factor too but I am so sick of feeling like crap. This is my first baby so I don’t know if this is all normal or what.
