First off, I think you need to stop bleaching, coloring and all chemical treatments of any sort. They aren't doing you any good and are probably causing at least some of this. You don't say what race you are (as there is a definite difference in overall hair type and usually in resiliency as well, not to mention the products that people often use). But no matter which one, I think you're causing damage with the bleaching and coloring. At least stop them for a while and see what happens.
As for wet combing, actually, things are often weaker when wet. I'm kinda wondering if you're conditioning (you don't mention that).
Also, I doubt you can do anything about the ends, so you may as well get them cut off. I realize you don't want to be down to nothing. How short is short? Me, I've got straight hair - shorter than about Calista Gingrich length and it starts to look too boyish. But Beyoncé can get away with much shorter. So again I wonder what your hair is like as you may be able to go rather short and still look very feminine and pretty, while everything sorts itself out.
I am no professional so please take this with a grain of salt.
