Dear Lara,
First things first, i Apologize, It seems we missed your post somewhere and did not reply you. My bad.
Thank you to see someone looking for a Friend than an Ex this time. 
Making a Friend is indeed an art (i meant a Good friend), at the same time, its indeed no Rocket Science.
You did not make any friend, is no Way a Curse. Its too too extreme to think. I have number of friends which i can not even handle, does it mean am Overly Blessed?

To be honest with you, do not worry of how to make of Win a friend (You need not be a "Friend P leaser"), Worry rather for
what is he Purpose of Life?
what you want to achieve?
what if your Passion?
What makes you the happiest moments of your life?Honestly speaking, the moment you find the answers of the above few questions, Friends, Money and abundance will come along. Its so Natural.
