Fearing the future

Days like today make me fear the future. Haven’t had a bad migraine in about a week, just little ones that meds easy took care of, then today a L9 migraine with all the symptoms except vomiting. If the migraine itself wasn’t bad enough it triggered a fibro flare. Every inch of my body hurts on a level that I can’t even describe. Then because the weather won’t decide what it’s doing my arthritis is flaring. My fear comes from older people telling me it only gets worse. How am I going to be a good wife, mother, friend, family member if the pain gets worse? Today just to survive I took migraine and pain medication 3 times. Just so I could function on a minimum level, not function well, not even hide it, just get out of bed and do what I had to. 
But then a small part of me says you will get used to it. You’ve gotten used to the daily migraines and fibro enough that most people don’t even know. I’ll get used to it. Such is life and then you die.
