Paysach Krohn in one of his shuirim says something so sensible. Comments people say will only hurt you if you let them! Let it go right over you. It is very difficult but it can be achieved with practise. I write this from experience. I have had my share of insensitive comments and the first 2 or 3 may hurt but I try and have succeeded in letting hurtful remarks go over my head.
I just think now that people who say these remarks are “nebech” or a “Rachmonus” themselves.
