Beamer,I ask myself often why? Why me? I asked my Psychiatrist back in 1982 when I had my first Panic Attack and was dx with Anxiety/Depression why? I asked God, why me, when our son died in a car crash, and most recently I ask again, why me, when I was dx with a terminal illness and the only answer that came back to me was, "Why not you?" 
I still have days where my anxiety rules no matter how hard I try and those are days I just do my very best to get through using the skills I have learned, knowing that majority of my years and days are good days. I have a bit of anxiety sitting around waiting to strike but I keep busy until I am so tired that it feels ok for me to rest, watch TV, read and know that I have stay in the moment throughout me day.
I hope this helps as it is the nature of anxiety to sneak up on us after we have had lots of good days.
Keep talking with us as support is very important. Post whenever you feel up to it.
Kindly,
Kitt
