First of all, sorry to hear you are feeling so poorly!!
And those beautiful babies that we love so much have totally sucked the sanity out of us lol.....I have always been a little highstrung most of my life, but after I had my son, thats when the shizzle hit the fan.....it started out with postpartum depression, and then became really severe....Doc put me on Lexapro and that cleared it up for several years.....and then.......no anti depressant seemed to work anymore.....fast forward to now, I was finally diagnosed with Bi-Polar II last year. PDoc said that it could have been lingering underneath all along and then the hormone changes after pregnancy made it rear its ugly head.....My advice is get back into your doc and either see if another anti-depressant may help, or get into a PDoc....you dont have to feel this way.....hugs to you!!
