I am so sorry you are hurting....I don't think you are "nothing" because you are something to us here. You are someone who deserve to feel loved and feel part of a family.
You can make a family amongst whomever you wish! If you want to include your friends here, that's ok. It is up to you.
I know what it's like to feel like you are nothing in a family. I was the same with my father and step-mother. I was my fathers' child and my step-mother hated me....I slept alone in the attic and had to take care of my younger bro and sis as well as do all the chores. Food often got kept from me if I didn't perform duties to her standards! Enough about me...I just want you to know that I can, some-what, understand and it SUCKS!
I want to send you lots of to surround yourself with!

Just so ya know...if you were never born I never would have had the pleasure of meeting you...or anyone in the "freewill" family....and I like you all!
