Help Fund My Dad's Funeral

My dad recently lost his battle with alcoholism. He planned on going to rehab the day of his death, but unfortunately he couldn't make it through the morning. I'm 15 and I'm unable to get a job, meaning I can't get money to help with my dad's funeral. My grandma is strapped for cash and I want to be able to help. I'm just asking for at least a dollar. A dollar goes a long way and can help me and my family give my dad the funeral he deserves.
