You are a GOOD MUM
You are fighting this, reaching out for help and taking medication.
You are ALSO caring for your baby, no doubt your dh too and recovering from pregnancy and birth.
I have ocd, I believe I've had it all my life and the research tends to back this up that it's innate. But I wasn't dx until Dd was 4 and I am certain that undx PND was a major factor.
The thoughts are not yours, they are this bastard bullying illnesses! Fuck it! Get angry at it, tell it to fuck off!
Meds are tricky it can take time to find the right ones for you and also it can take a while for them to start working and unfortunately sometimes they make you feel worse for a while until they start working.
I also agree with pp, something that's kept me going at my darkest points is knowing that if I did take my life it would make it so much more likely dd would also suffer depression and perhaps do the same. Not to mention the anguish loved ones go through after a suicide - even if they were babies at the time.
The BEST thing you can do for your baby is fight the bastard! Break what you have to do each day down into manageable chunks and try not to do too much.
Eventually you will be able to do more each day and you WILL get better.
It's a gradual thing and not every day will be an improvement - that's normal that's life, some days are great some are shit! On the shit days remind yourself they're not all and will not all be shit!
As for people not telling you you're a good mum in real life - it means nothing!
Men are so shit at parenting in our society that even doing the bare minimum attracts praise.
Ignore it!
Re smiles from baby - fake it till you make it. Babies just copy, if you smile he'll smile and as a bonus there's research that shows that even fake smiling improves our mood! Make a game of it, pull silly faces or whatever and you may well find it helps, as will seeing baby smiling back at you.
Please please keep talking/posting/reading whatever helps.
I have had MORE than my share of late night calls to mh services and helplines and on chat boards - anything to distract when I couldn't sleep. So do that, do whatever it takes to help.
Sending you SO MANY heartfelt wishes for peace of mind, good mental health and LOVE! We can never give or receive too much love. Love yourself as much as you love that baby you are worthy and special and kind and caring and you deserve to get through this!
