Welcome Ellen sorry to hear you had such a rough time. As someone who has had a traumatic first birth with an EMCS and a traumatic third ELCS birth (with major PPH and an emergency hysterectomy) 6 weeks ago, I can safely say that it does floor you in more ways than one and this is only natural so please don't blame yourself. Time is a great healer.
It might be worth you calling Birth Crisis, just being able to talk about the birth and how you are feeling can help. Feel free to PM me too if you would like and you feel I could help in any way.
Lack of sleep is a massive factor in how you feel post-birth. Things that I have tried to get baby to sleep on their own that worked for my three are: propping the head end of the cot up/reflux wedge, putting a t-shirt I have worn over the mattress, putting a hot water bottle in the cot to warm the mattress before I put them down, sleeping sitting up with baby in a sling on my front, DH wearing baby in sling while I nap, heartbeat sounds/white noise, baby sleeping in bouncy chair while I nap, taking baby for a walk in the buggy to get them to sleep then leaving them there while I nap or letting DH take them out in the buggy while I nap. There are also rocking devices that you place your buggy or moses basket on that get some good reviews such as Robopax.
Also because you had a major PPH make sure you are taking iron supplements if your iron level is still low because anaemia can make you feel very tired and emotional and just exacerbates how you are already feeling.
choco so glad you are ok and in less pain, that must have been very traumatic
frizz glad your DH has started to engage his brain and think about someone other than himself.
MrsV go for comfort, I lived on ante-natal ward in maternity leggings, big t-shirts/nighties, fluffy socks, slippers and a dressing gown for two months! I did have two outfits and a pair of trainers for visits to the shop/walks, you may want some outdoor outfits too as walking helps the induction process.
