Hi justherefornow1,
You and I have had very similar childhoods indeed. My first attempt as suicide was 6, drugs at 9 (dominated my life until 25 in one big blur), and basically lived in a place where no one touched, hugged, talked or showed any love for me. I cannot recall being hugged or told I was loved except for a few times by my mother when I was about 10...
I was lucky though to realize early on that you cannot pick your family and you cannot change who they are, what they think, how they act, how they feel...they all have nothing to do with you...it's them! You cannot change a person, they can only change themselves.But never forget, you are you and that you can affect change in. Don't let them or anyone else define who you are, and most importantly, who you can become!
You have a full life ahead of you. My advice is to search out those rare people that shine a light in the world, that have hope and love to give and to learn from them. They are out there! Hopefully you can then do as I did and find your real family in great people you can call your real friends. I am 43 now and my savior was a life long friend I still keep in touch with to this day 30 days later who changed my life. She showed me that I matter, that I must learn to love myself and all that I am, that we are all beautiful inside in our own unique ways.
Now I am very religious myself (a result of the realization that I really need so much help every day I think =)) and I don't want to sound preachy, but you will find many of these *shiny* type of people in church youth groups going through the exact same thing you are! I am not kidding!
Best of luck in all that you do.
