PP Depression

Samantha
I'm new to this hormonal sadness and anger thing I'm going through with my 2nd child and I've already scheduled my 2 week check up with my doctor in order to check this emotion out. 
I'm 1w3d PP. 
I'm crying randomly, stupid stuff seriously pisses me off and I'm livid for no reason, I don't want to do anything and I'm hyper sensitive. 
This isn't everyday, it's random.. 
I know it's different for everyone but how are you ladies coping? Medication? Therapy? At home activities? 
I need some sort of direction on what's best. I'm worried about medication..
