I am sorry you are feeling down, but I have also heard that people become depressed after surgery. It's almost like having post traumatic stress disorder, so give yourself a break and speak with a professional if you feel it would help.
With regards to people not calling, I think that is common. People are caught up in their own lives and seem to come around when something big happens, like your transplant, then they get back to themselves. I have a handful of friends that do still care and call me to do things. Lisa (from this site) has always been there for me. But others can really surprise you. I haven't seen Gio in over two months!! This is a kid that practically lived at my house for 8 years!! I have tried and tried to see him and he doesn't want anything to do with us because he says it hurts him too much. So I patiently wait for him to come around, but it is less on my mind now, because as Lainy said, it would drive me cuckoo if I dwelled on it all the time. When you are over the hurt, get in contact with these people. They might be giving you time to adjust. I'm sure they still care, but if you worry about it and feel bad about it, it will just eat you up. Enjoy your time with your family and just be thankful to be alive!! Take care.
My beautiful daughter, Lauren Patrice, will live on in my heart forever.
