Just another thank you to everyone for your lovely replies. I do feel incredibly lucky, not only to have a very supportive husband and great support network, but also to have found such a wonderful group of women here who I can refer to, question, and ask for hugs from!
The rest of today has been really good. A few anxiety attacks, but i've been able to cope with them myself which is great, and gives me so much more confidence that I can beat this! I've also finally been able to eat a bit more substantially today which is a relief - long may that continue!
Hopefully we'll get another good night tonight (he went 4 hours between feeds overnight last night!). That will help me feel a bit more human again!
Oooh, and we had him weighed today, he's lost less than 3oz!
