Trish,
I am sorry for what you are going through. We handle stress much better as non-smokers. You owe it to yourself to give yourself a life free of that poison.
Anybody that puts alcohol or drugs before their kids doesn't deserve to be a parent. One day, those kids will realize exactly who was there for them. Who throws their kids out anyway? I don't care what happens, you stand by your children no matter what. You sacrifice whatever you need to, to the kind of parent your child needs you to be. Alcoholics, there is nothing you can do for them or about them. All you can do is try to develop boundaries. They create so much havoc in the lives of the living. Yes, I said living, whatever it is they do, it is not living.
I grew up as an adult child through one parent and then my mother turned into an alcoholic after quitting smoking. She turned from a hyper critical not exactly maternal person into a nasty spiteful witch. I think you know my son has a form of Autism and ADHD. She blames it on me, yeah I caused it, geez. When my son was younger, she called social services on me because I didn't have him on medication. They told her to go pound sand. Four weeks ago today, my son who at 5'8" is 5 inches taller than me, assaulted me pretty bad when I refused to budge on a decision. He had been given a medication for an injury and coming off of it made him angry and super aggressive. Normally, he is not like that. I made the mistake of calling my mother for help afterwards, thinking you know my mother would see me bruised and bleeding and try to help diffuse the situation. So, she called social services again because this was my fault and he shouldn't be on medication. Can you spot the contradiction? They must have her some sort of list for people with ulterior motives or something, because nothing came of it. Funny, none of the professionals feel the way my spiteful mother does. In fact, they marvel at how far my son has come. That was due to sacrifices, research, hard work and decisions made that came from me, nobody else, least of all my mother. Not from the once in blue moon father of his that will take him to the movies, but I have to send money to make sure my son eats. Yeah, got that covered too :)
I am sorry this turned into a rant of mine, I didn't mean it to be. I was trying to relate and went overboard, sorry. I didn't smoke though Trish, it does nothing for you. What does a cigarette do for you? Can it change your husband's ex? Will it make your problems disappear or will it create new problems? We love you Trish, please quit today. Any support you need, you know we will give it to you.
