All of the games you bought are still on BF. You can to go to the your account tab then to purchased games. You will need to re-download them, but once purchased, the games are yours forever. The only way to avoid this happening again is to transfer your games to an external hard drive(I think, I'm no techie).This happened to me also. I feel your pain.
There will come a point in your life, when you realize what really matters, what never did, and what always will.
