Leaving me behind

When i was little i use to have these dreams, i would wake up and look around me to only see that im all alone. I would scream and scream but nobody is there. I kept having these dreams repeatedly. And now actually being alone. To those 2 people that are suppose to never ever leave your side and always be there for you, why are they leaving me ? Why are my dad and my mom not want me anymore and leaving away. They dont even have a single grudge to stop. Cant they see im lost, cant they see i dont want them to leave? They never care. I'm only 15 and they are giving up on me just like that without even a fight. Letting go is easy but holding on is hard according to them. I even found out this year that I was a mistake, my mom had 2 aboortions let me repeat that not one but two! to have me out of her stomach and from the world. When i was born all they would do is fight. Then this other day my mother said "I cant picture life without u or u never being there." I cant believe that i thought she really ment those words. Words can mean so much but so little, we choose to believe lies to hide the truth because it hurts. Sometimes you have to face the fact that your not wanted in this world.
