I had a friend who wanted to commit suicide because everyone made fun of his weight. He came to me for help and I told him to never ever give up cause in the end it gets better, he's now dropped 120 pounds and plays for his schools football team.
My friends and I went to Beacon Of Hope, a place for mentally disabled people to socialize with people like them, and helped out in the kitchen and played bingo with the people there. We met people who we will never forget and had a lot of fun.
Honestly, in my short fifteen years of life I have not yet done anything monumental, but I make it a point to try and be nice to everyone because I believe there's simply no place for hate in this world. As Dr. Seuss said, a person's a person.
During the holidays I go to a warehouse and pack grocery bags, I then deliver the bags to assigned families who can't afford what they need for the holidays. It's amazing to see the looks on their faces when you open the door, they're so grateful, it melts my heart.
