New mastectomy yesterday

Hi I have just have a left side mastectomy and am still in hospital, My sentinel node was clear I am waiting to go home. I don’t know how i feel apart from scared.

I get the next steps on Nov 10th at my follow up appointment.

my consultant used glue only on the op so my wound is not covered at all. Has anyone else had this done please and what issues should I look out for .

is this better that having drains .
