Ziutek I am sorry for your daughter and for little Klaudia. It's already terrible when an adult take his life, but when it's a child it's much, much worse. I've lost a schoolmate like this, we never knew he was suffering, he was always nice.
I've read a few books of the after life thread, and children are always taken care of, even if they take their life. No one is abandonned.
I also read the testimony of a jewish couple who had died in an accident a few years before the holocaust. When they arrived in "Heaven" they were told they had agreed to die to help all the jews who would suffer and die in the years to come. So maybe she chose to go to help on the other side. In any case, I 'll pray for her to find her way.
