When someone ask me why you don't have many friends. I answered you're right, I only have one. 

Just one he said, yes I replied. 

Why don't you try to make more? 

I tried, but it's not easy. 

Why? 

Imo, a friend is someone who help you to rise and to grow, not holding you back. I had so many people that were trying to get close to me only to leave me once they get what they wanted. 

It's easy to be friends when things are going well, but when it's not.. You'll know who they really are.
