Hi kid. Read my profile. About you're mom. Mine was bi-polar before it was cool. No tx just deal. Good dad just never around (working to support us). Still, that left my little sister and myself totally in the care of my mom. Not cool at all. Never physically abused me or tried to hurt me but everyday was like walking thru a landscape full of landmines. Good times. No friends at school, no understanding or support to be had. After about 40 years I discovered that my mother did not ask to be born bi-polar and did the best she could for us. In her own way she did love us. I'm telling you all this because it sounds to me as though your mom has some real problems that have never been diagnosed or addressed. I believe you are making the right decision to keep your distance for now. Right now the most important thing for you is to get your head straight and be in a good place. You could not help her if you wanted to (sounds like she needs professional help), but she can do more damage to you. Maybe someday she'll get better, maybe she won't. That will be up to her to seek help and tx. Sorrry about your sister. When you're young sometimes it's hard to see everybody's side. As you age you realize everything is a gray area. Hope you and your sis can resolve your differences. But for now,concentrate on yourself and your relationship with your dad. Best wishes and good luck from an old lady.
