You could be holding yourself back and the drink could be holding you back. It could be both. For me, I knew that alcohol was producing seriously negative affects on my well being mentally, emotionally, spiritually and physically.
Time heals. Time and patience. Time and working towards a different outlook on life. There is something to be said about our thoughts. They can keep us trapped or they can empower us. Thoughts can serve as a positive or a negative. Choices. Lots of choices.
If you give yourself some time, and make adjustments in the areas of your life that you are not happy with, I am sure you will see an improvement. Life is so much work.
