So sorry to hear this Kathy.. I (we) have just finished our 2+ yrs of this same diagnosis.
Buckle up, I like to stay positive and I find strength in my faith. This won’t be easy but you can do it.I found instant potatoes were a big hit, you can add butters and cheesy sauce for added calories, there are also a few high calorie drink powders that were life saving for us when he just couldn’t eat enough.We used Mass Gainer, affordable and very high in calories. Make smoothies and shakes, add in the boost for nutrition.the shakes help with the taste.. This is a good , helpful site , just know- no two cases are the same.my husband still has issues Neither his surgeon or Oncologist can address.. But it’s treatable and you’ll figure so much out as you start living it.. God Bless you both
