so tired

I don't know how long I can take this daily pain and fatigue.  I am not sure which is worse.  I am already beyond tired and then I take pain meds that double the fatigue and double the brain fog.  I have not had a pain free day in so long, I almost don't remember what its like to not have pain.  I have stopped telling family and friends how I feel because I feel embarrassed.  How can I be sick all the time?  It doesn't seem like people understand.  When its not an illness that can be seen, people don't take it seriously.   I so badly just want a day that I can wake up and feel refreshed and pain free.
