Based upon years of being left and forgotten in many areas.  
It's hard for me to trust and make any friends anymore.
I barely have established a stable relationship due to issues and past of being cheated on, abandonment, being ghosted, and always being that someone who was never someone's first choice or friend.
And yet, I still love and get too easily attached.
I can never be angry or hold resentment...
I just wish others who know this pain, didn't.
