Hi Mary, sorry to hear you're feeling a down, hormones can be a bugger can't they! You did really well to give Isabelle 11 days of breast and you shouldn't feel bad for stopping, you've not failed, that you are both happy and content is far better for Isabelle than breast feeding her.
If the constant visitors are getting too much, ask them to give you a break, I'm sure they would understand that you need to spend some time alone as a family, ask Hubby to talk to them if you don't feel comfortable doing it.
Try to keep your chin up, I bet you're doing a fab job, and Isabelle definitely thinks you are...the hormones will settle soon and you'll start to feel better, but if you don't then make sure you speak to someone, including us!!!
Big hugs from me and Henry!!
Lins
