Goq, to answer your holocaust ques, I can see that your relative wanted to point out to you that you can succeed despite all your hardships.
But no, I don’t think the Holocaust, and other’s day to day Tzaros have anything to do with each others.
There are nebach enough people who haven’t gone through the holocaust, but have been through their own h*ll.
And maybe we should all take a lesson from holocasut survivors, who rebuilt their lives and started from new, after so much suffering.
If they can, we all can too!
