Ugh,if you read my other posts, then you would know what is happening. My stupid mom's husband just kicked my dog in the face. Its been hard to control my anger toward him. If he ing does this again, I will shoot him in the ing face with my bb gun. I don't care if I go to jail or a crazy home, it would be better there then living here. I hate my ing life, I wish I could leave or just die.:(:mad:

No need to use violence, merely first report this to the police and tell what is happening to children and family services

You are not helpless, and you are not without options. As Chuck said, get on the phone, and call the police. File a report. Speak to a counsellor, your Doctor, a shelter, kid's help phone, your church, a responsible adult, a relative, neighbour, a teacher.

Do something before this repeats itself.

It sounds like you're pretty unhappy with your situation.
There have to be options... and if not then there has to be
A better way for you to respond that will promote happiness in you and those around you rather than this misery--you can respond in ways that affect change without violence.
You need to know, it's against the law to say what you said (about the BB gun in the face)... it's called "communicating a threat". You could end up in some trouble that you want no part of. If you think it sucks where you are now--jail or prison would be a heck of a lot worse. So please, be careful where you let your thoughts go, be careful what you say, and start to look for alternatives for your living arrangements and your activities.
Maybe you could go and volunteer at a local animal shelter. You would have a place to go where they will always need you. Network, make connections. Life is full of possibilities. Think. : ) I'm sure you'll come up with some ideas.
I hope the best for you.
