Oh, what a terrible shame! Bed bugs are so hard to get rid of. I remember seeing a program on tv (infested, I think it was called) where a lady got some cheap second hand bunk beds for her young sons and it contained bed bugs. From there on after, she could not get rid of the bed bugs despite all her attempts. I believe they really only come out at night time when they smell the body sweat etc so by morning time, you are riddled with itchy rashes and irritable bumps. I do hope you are able to get it under control because life must be unbearable.
