PPD...

So my son turned 3 months the 13th I had a regular drs appointment. Apparently the Postpartum Depression snuck up on me, now she wants me back on my anti depressants and anxiety meds (I was diagnosed with anxiety and depression almost 7 years ago I went off my meds after 2 years) with once a month counseling session.... I haven't been (to a therapist let's call it what it is) since in 17 years (I was 7) so I'm not sure if it'll work cause I didn't work back then. I try to self medicate but that don't always 100% work. Anyone else on meds and having to see someone?
