I have post natal depression and wasn't diagnosed for 2 years, 2 years later i still have it and can't loose the feeling it will never go away :(

I never discovered I had Postnatal depression until it was too late!! My relationship with my 2 boys father went down hill and the kids and I moved out. I felt like the world opened up and I was alive again. But it soon came crashing down when I started experencing  panic and anxiety attacks, they were horrible. I would start to hyperventilate and couldn't catch my breathe which would make me go into a panic and I would be sobbing and crying for help this could go on for hours. have you ever experienced that? please lets talk about it
