(((BatsandButterflies)) this is no environment for you or your little brother to grow up in--
I know I read Leed's reply and say YES- Call the cops, but then again I also know how hard and scary that may be- but sometimes it is what is needed....... hell even as an adult I was unable to call the cops- but at least as an adult i could leave- you are still growing up, you do not have that choice and by no means am I saying you should leave on your own-- but something needs to be done. This is not a healthy environment for you or your brother and mentally does not do you well.

My older sister to use to take me to a neighbors and their parents would call the cops when domestic violence would occur... do you have an out lit like that or an other older relative that you can call when things hit the fan?

Many Hugs to you
