Welcome -
Sorry you have to be here - but you are always welcome to vent. I also had a neuroendecrine carcinoma, although mine was a typical carcinoid. I had a rough time breathing after my lung was removed, too, and was on oxygen for about 5 months. I think you are pretty normal - it just takes time to heal and get your strength back. One thing that everyone stressed was as soon as you are able - walk. I know I had a hard time doing 2 minutes on the treadmill, but now I am back to my "before surgery" walking. There are still days when it's harder than others, but I have been trying to still walk.
As far as the chemo after surgery, well I think that's up to the individual. I was told it wasn't necessary because of the kind of tumor I had, but I did have chemo before surgery. With all of the strides being made now with the drugs and the way they are administered, chemo was nothing like I expected it to be. It was, for me anyway, very tolerable.
Being depressed is a totally NORMAL reaction, I think. You have been through HE*$ and back - but here you are - a SURVIVOR! You may not realize it yet, but perhaps you will inspire someone else who has just been diagnosed. Perhaps their family just got the news and don't know where to turn, etc. You are here for a reason - so come and share with us - we are glad to have you. I will keep you in my prayers as you recover.
