Appetite

After my first birth, I had no appetite for a year and was depressed and raging. I didnt even know it was a problem until after so i was not on anything. Now 2 months post second, no appetite again. Im on prozac for anxiety which i feel is controlled but my appetite is non existent. Only been on prozac for a few weeks so the no appetite started way before starting. I could go days at a time without eating. I have no idea how to change this or help myself. Who do I even reach out to for help. Is tbis just normal ppa symtoms because I would hate to go another whole year feeling shaky and weak
