Healing after major cancer surger

Let me tell you, being a juvenile onset (type 1) diabetic and healing after  any type of Major surgery is a pain.  I don't know if cancer surgery makes it worse, but I have had a few other major surgeries, and I didn't feel this useless after them.

I've been told by my surgeon and everyone in his office, I have to eat lots of protein and vitamin C to help me heal.  And not to lose weight so quickly.  BIG problem there.  I'm not hungry, so I'm sorry, but I can't help it that I'm losing weight.  And besides, it's not like I don't need to lose 100 pounds because I do, and I've only lost 40 pounds since my 2nd surgery on June 25, and most of that has been the 20 liters the surgeon had given me during surgery.

I try to eat a lot of protein, I've even tried the whey shakes.  Whenever I have them, I don't want to eat anything for supper/dinner.  They fill me up too much.  Adding some whey powder to other foods just makes them taste funny.  I added some to my pudding and it just tastes icky and I love chocolate pudding.  I have been eating my yogurt for breakfast, but I can only eat a 1/2 of a small container.  I can't do a full one.  When I eat what everyone considers a good amount, I feel miserable for several hours.

Everyone is happy at how well I'm healing, and they are surprised too.  Juvenile onset (type 1's) even those of us who are in good control, do take longer to heal than no diabetics.  The doctors are just amazed at how fast and how well I'm healing. 

I just want to be able to pick up Bear, but I can't because he weighs a little over 10 pounds, which is my limit.  Sure I could pick him up and do more, but I don't want to injure myself.  I've seen too many people not pay attention to what their doctor told them to do and I'm not going to injure myself.

I'm also very impatient.  I think that's my biggest problem.  I want things to be over and done with.  I want things to be healed so I can do what I had before I went in for my surgery on May 20th.
