One thing I love you already by how strong you are, it takes an emensely strong lady to go through what you have, and I shall say I'd love to help(:
I am very sorry about the child, it must have hurt dearly. Another thing, I say, though it may not seem like it yet, you are MOST DEFFINATELY worth breathing, every breath!
I know you are having some very negative experiences, but as a friend you could possibly try to vent all of those negative feelings out by possibly talking to somebody?
[the pastor, a friend, boyfriend] or find an outlet?
Such as music, tv, a sport you possibly enjoy?
I can say you've already mustered trying one; talking to somebody; Teen Line:D
But all in all I am very sorry for what has happened to you, and I do care. I promise, someday, somehow, it will get better. You just have to find the light at the end of the tunnel.
I'd love some feedback!:)
