Gina,
That's a great attitude!
WE ALL get down.
I've had rsd since '83.
And, even though I feel I have the best doctor, and care, I still have more down days than up, or should I say, everyday, I get some "down" time....

Special events, like your family visiting, tends to give us an adrenaline burst, and that can really hurt, once it passes!
I hope that your sister has the time to "listen" to you..
That's what you need to ask for from her.
Let her know you're more frustrated than she is! (I'm sure you are).

You will get through this.

Blessings and peace,

Pete
