I am very sorry you are having problems with your family, sounds to me like its more your dad and your brother and you are stuck in the middle of it. I hope you find a job soon and are able to move out on your own and then you can deal with it on your terms.

Hopefully you have a pdoc, (someone wrote you the lamictal script), talk to them about finding different outlets so its not just video games.

Lamictal is a great great thing for most of us, but it is very important that you don't increase or stop taking it all at once. It needs to be trickled both up and down, and it would probably make you feel much less edgy. Please don't stop taking it cold turkey.

I hope this all works out for you, sooner then later! Keep us posted!
