I'm sending gentle hugs. My wife told me today she want's me back. Like you I have had a flare for a few weeks that has me just dropped down to nothing. My personality and comunication skills went into hiding as well.
The only advise I can give is some I need to take myself . Talk to your family, even if the only thing you can discuss is how you feel (emotionally and physically). Laugh a lot; find joke or comedy sites on the internet. Try a craft, this helps me with concentration and fine motor skills.
I hope you get through this flare soon.
