Time for change but what first?

It's been a long long day. I'm really not used to feeling this much angst. My mother said something in the car that was not only an attempt of making me feel like a child, is sort of emasculated me too. I almost responded it to it and then i just knew it would only start an argument. No my sister has taken too many ambien and she is flitting about the house like she is on major speed. My ability to meet calamity with serenity is gone. I know there is a way out of this but I can't seem to find the first step toward my adult life. I'm not using over it but I also don't plan on feeling like crap because someone's insanity-not my own. I'm sick to shit of my sister being fucked up , the trip she took was so relaxing for me. lol

I love to get an idea across

My mother has never understand the principle of my using drugs even though it's never gone well. She has a  digestive system that can't tolerate milk or ice cream, but once in a blue moon she's eat/drink some and then is really quite ill. Perhaps once in the last 365 days she has used a dairy product and gotten away with it. 95 percent of the time it will make her sick, she knows it, it isn't new but she does it anyway because the taste is good. Sickness follows and she says never again.

Now I know, lactose intolerance is a stretch comparing it to drug abuse, but the insanity is just the same and I have been looking for a way to help her understand the insanity of thinking she can get by with just a little ice cream is the same way I hope I can use a little dope and get away with it even though history says I won't. Just looking for a bridge to help understand each other. When you speak different languages of understanding ANY bridge that covers some of the gap is a good thing.
