Part of what you are feeling is the need to belong to something bigger than yourself.
Alcohol deadens that. I was in a fantasy...party world. I was partying, so who cares what anyone else was doing. That led to my physical deterioration.
When I quit, my emotions would come rolling in. They were horrible. At 16 months clean, my emotions still have a large impact on me everyday. I get so negative thinking about the way I see things in my life. I keep telling myself to not over react, I am still healing. Still getting used to normal emotions.
SR saved me. My class, all my SR mates All of this made me feel like I belonged somewhere.
You belong here to. Help someone daily, I try to help several folks a day. When I do, I feel better. This leads to a chain of happier emotions. I sleep better and stay healthy.
I also took up a hobby. I group hobby. AA is fine. Like minded folk. Consider joining the dance group or a card playing club at the local YMCA.
Thanks for the post. Hope this helps you.
