Your not crazy...
But as long as your around an alcoholic, it is a family disease and you will also become sick by being round an active alcoholic. In hindsight, I can see how sick I used to be only by looking back now after a lot of time of no alcoholic in my life. I was quite crazy.... I am not the same person I used to be at all.... I'm free now and found a great deal of peace.
I wish you the best through your journeys, loves to you always...
