An energetic police officer I once knew used to always say that:
"Every day above ground is a good day."
(He used to also say that it is better to be judged by 12 than carried by 6, meaning take the shot to save your life now and worry about the rest later)
Shortly after he told me that he was shot and killed serving a search warrant, leaving behind a pregnant wife and 2 kids. I am certain his wife did not agree with that quote for a long time after his death.
There is zero comparison to your situation, except that you can still fight the good fight.
I always always remember what that cop told me, he used to say that when someone was feeling down or needed a boost. Usually he just made people mad when he said that. Mad enough to fight. Never ever give up. You are almost at the end of chemo. You made it through, almost! Chemo drains your energy, all of it. Just going to the bathroom alone is a major event. Once you finish chemo you'll be amazed at how quick you bounce back. Think about those extra 10 pounds as your body's way of saying that the chemo isn't killing you, only the cancer. Otherwise how could you gain 10 pounds if the chemo was slowly draining away your life? Now you have the perfect chance to start over. Gaining 10 pounds is good for you in this case. It gives you something to focus on. If you were really really skinny, why bother exercise? Now you feel you need to lift, to get back that muscle so you can lose that 10 pounds.
Eat clean and healthy. Easier said than done, eh? Dried seaweed may be good for you, but tastes much better when fried and salted like potato chips and eaten with rice (yum!). Try probiotics (see
www.mercola.com for lots of usable, healthy tips to help you regain your health). Think about different hairstyles once your hair grows in, hairstyles you may not have tried because you found one you liked and stuck with it over the years with little variation. Get back into life slowly, at your own pace. It could be weeks and weeks after chemo ends before you feel like you are happy and might want to consider bouncing out of bed in the morning.
Congratulations on almost ending your chemo, and welcome to your new life!
