Mood dissorder? Ppd? Anxiety?

Okay ladies I've come here to see if anyone's has experienced this I'm going to call my doctor on Monday and make an appointment just to clarify I just want to get some of your guys's opinion since I've been having these mood swings like I just burst into tears out of nowhere and just feel extremely sad lonely suffocated and just sad another time I'll have these bursts of energy where I just go go go but then when I sit down I'm mentally drained and sad. I can be perfectly fine for days and then have a bad day or to. I used to self harm, but i havent in so many years. Sometimes I feel like I want to but I do have a 9-month son and hes what keeps me going and reminds me how precious my life is. He needs me.
