i'm sorry to hear that.
perhaps you can meet up old schoolmates?
rather than mingling at bars or discos which picks up bad company.

i see.... how about sports?
do you do any form of sports or exercise?
that is another way to meet new friends.
but caution, a broken heart can lead you to wrong directions.
take a break to heal the pain.
i would suggest your family or relatives would be a good listening ear.
