What is the best way to stay positive about situations which are tough?!

Here's what I do:
I had a huge fight with my aunt. She's 18 and I'm 13. She's a wanna be gangster, and I'm a girl with a dream of being a fashion photographer. I say to myself:" you know what? I'm the one who's going to college, not her. She had her chance! I'm going to afford things, not her. "
Hope this helped you!

My entire life has been tough. It's a long story, too long to explain.
Anyway, when ever I start thinking about my bad life, I always think of things that are good about my life, like a family and a roof over my head. Sometimes I'll stop thinking about the present or the past and I think about the future. I know things will get better.

Just focus on the good things in your life that you're thankful for. If you really need to, find a religion that best fits you (but religion is for the weak minded).
