You aren't useless....NOONE is useless! You wouldn't have been put on this earth if you were useless. I may be 16 but I am so much more mature than a lot of people give me credit for, and I know so much more than a 16 year old should, but let me tell you one thing. This is to comfort not hurt. You are not useless, if you were useless, God wouldn't have put you here, you wouldn't have the ability to live. Things always get better. Take it from me. Losing hope is not the wisest choice you will make in your life...trust me, it's one of the worst things you will ever do.....EVER!
