Hard to Eat

I had done RT (Radiotherapy) for 25 times. Now, it took me about one hour to finish a meal. My chest was pain whenever I eat. This is the side effect of RT. I need to eat a medicine to numb my sore throat before I start my meal. Normally the numb feeling will gone before I finish my meal. Eating became a big project to me and I get to know that eating can be so hard! I feel jealous to all my family members whenever I see them eating so yummy so easy. I really can't enjoy food at all for the moment.
