Animalnurse, I live alone too, and sometimes, when it's late and all is quiet, is when it's the hardest. Our thoughts can be our own worst enemies it seems.
I tend to be an over-thinker, and it really sucks. Where some people can make a decision and move on, I agonize over the smallest of things. So, imagine what happens with the large things.
But being drunk didn't help. Though I didn't really drink to hide my feelings or avoid problems, when drinking I certainly didn't work on resolving them either!
Now, like today, I can wake up to the sun, grass wet with dew, a fresh cup of coffee in my hand , and look at my problems and thoughts with a clear mind and realize that I at least sober, I can begin to tackle them and not let them hold me hostage.
