I’m in the same situation, husband abusing drink and cocaine. His personality has completely changed toward me because of this.
I don’t consider myself selfish because I feel I need help too, coping with him. After everything I have done for his family and him, I too have also been tossed aside. My feelings don’t matter any more it’s all about him. I have never known him so selfish and uncaring in all our married life. I feel used and feel I have been disrespected.
I too cannot sleep or eat. it’s affecting my job as I cannot concentrate. My mind never stops its on overdrive day and night.
So yes I’m in the same boat, I’m just thinking that in time I will come to hate him for what he has done to us. Bad I know but I actually cope a little better if I imagine my husband to be dead and then I can think of our wonderful life before. I can then cope with this thing that has replaced him a little better.
All I can do is hope my husband returns as quickly as he disappeared.
