Step mum's that have to deal with evil step kids.

Hello all, My name is Samantha I have 4 children 2 which are my own and 2 which are my step kids. My step kids have been bought up by a heavy drug taker that has bipolar and drug induced schizophrenia. They now live with me my husband and my 2 kids and are very much like their mother.They are only 9 and 7 years old but have the thoughts of a not all there adult. I have experienced just about everything most people would not even think a child would ever do. I now want to help anyone that is in need of any help when it has to do with their step kids. Please don't be scared or embarrassed to ask because trust me when i say it wouldn't surprise me with anything a child is willing to do to be mean.
