Working with ankylosing spondylitis: Is it possible?

Hi, this is my first time back on the site in a long time.... 

I was wondering if any of you still work? I was diagnosed many years ago and I was lucky in that at first my AS wasn't severe enough to keep me from going to work. But lately I'm going through a bad flare and I'm having a hard time keeping up with everything even in home office.

I really don't want to have to quit, my job really gives me purpose and I think without it I'd be very depressed. It's kind of my only form of social life since my family is far away and I don't have much energy anymore to go out. And needless to mention I do need the salary. I guess I'm wondering if anyone else has been through this and if you have any advice on how to get through it?

Thanks xx
