Hi natsyloo.
Congratulations on the birth of your baby!
It sounds like you are doing amazingly well. Firstly, you have acknowledged your depression and anxiety, and are getting help. That alone is a hugely positive step. It's also great to hear that you have support around you. Stay open, keep talking and confiding in your nearest and dearest about your feelings as much as you feel able - just do not feel you have to cope with this alone, that is my number one piece of advice to you. PND is incredibly common, as I'm sure you are aware. You are not alone, and YES, you will come through this, with a bit of time and the right support.
I had crushing PND with my first child. Like you, I had a good pregnancy, my baby was very much wanted and I was feeling very positive about the whole thing. Also had a supportive DH and family, and all should have been plain sailing on paper.
Unfortunately, I also had a traumatic birth and was physically unwell afterwards, which affected my ability to breastfeed. I ended up feeling exhausted, highly anxious and, when I look back, very shocked by the brutality of the whole experience! I didn't really acknowledge that I was unwell until about 16 weeks in, when I couldn't keep up the facade any more and found myself in constant floods of tears all the time. I just felt so hopeless and so anxious. It was a very bleak time, looking back.
I wasn't really able to get out and about and face the world in the same way you are doing, and I think it's great that you are making the effort to socialise, exercise and generally keep on keeping on. Just go easy on yourself. You don't have to 'cure' yourself overnight. Baby steps, one day at a time - that was my mantra, and I think it's a good one.
Meds didn't work for me (although they are hugely helpful for many women with PND), but counselling was helpful (although it took a while and sometimes felt frustrating and even painful) and exercise was almost magical (must be the endorphins). Time was the biggest healer, though. I found it took me about 18 months to really get to grips with being a mother, and probably a bit longer to properly exorcise the ghost of my horrible birth experience.
I went on to have a second baby (better birth, no PND), and my oldest child is now almost 6 yrs old. To be honest, as hellish as it was, I think I am probably a stronger and kinder person because of my PND.
Good luck and am happy to chat any time x
