Anyone else self with this ?

I'm a FTM I've always wanted a baby loved taking care of them growing up and I just had my baby girl almost two months ago I love her to death but lately I've been feeling horrible I can't stop crying I can't manage to do anything without wanting to give up I tell myself I shouldn't of had a baby or I can't do this anymore I've thought about leaving the baby with her dad and just running away here and there I think about doing stuff to myself i cant get thru the day without crying or being rude or mean  to my husband for no reason. Some days I'm fine and some days I want to give up. I talked to my step mom and she said I have post partum depression and I need to get help before I unintentionally hurt myself or my baby. I've never thought about hurting her. I'm going to the dr Monday morning I just don't know what to expect out of it or anything has anyone ever felt with this or experienced this ??
