Hi Fairy, Don't worry, you've take a big step forwards accepting that you need help. That's the hardest part, it really is.
Next, step away from google. You'll scare yourself stupid and stop doing the things that can make you better.
For now, be very kind to yourself, eat well, get out in the fresh air at least once a day, and try and sleep (often easier said than done).
I'm still on my journey, I was diagnosed with PND 19 months ago and have been on sertraline since, and I won't deny that its been hard. But you can make steady progress to getting better, it is slow, and you will have ups and downs. Are you able to access any counselling? I found one of the hardest things was opening up and talking to people about how I felt, and having a stranger to talk to seemed to open the flood gates.
There are lots of us out there, please feel free to PM me if you like.
