I really do envy you man. I honestly never had a childhood. My teenage and innocence literally fled so fast, that sometimes when I think about it; I never really did anything in those years because of my family issues. Regardless, now that I am in my twenties, I do feel really doleful due to the years I lost. I say, enjoy this life. Your childhood will end sooner or later. Better to plan for a good future ahead. That's my advise.
You sound exactly like me... I sympathize.
