Hi Stefanie
I am happy that your cancer is one that is curable. Thank the Lord for that.
I am unhappy that another Mom has to face the fact that her child is addicted.
That said, there is nothing you can do to change the situation he is in right now. You can change only your situation and you really have to save all your strength for you right now.
Your son is an addict, like mine, and until he is ready the only one he cares about is himself and where he will get the next fix. This doesn't mean that he doesn't love you, it just means that his addiction has taken over his mind and body for now.
How many times did I say, "my son doesn't love me" because he is so hateful all the time. He treats me horribly. He yells and swears and calls me horrible names. I cried all the time because he broke my heart. Later I finally came to the realization that this was not my son, but an addict.
First things first now! This means you must take care of you first! You are very important and worrying is not going to help your health at this point.
Prayers coming your way that you regain your health quickly!
Hugs, Devastated
