Good stuff man. As Dee said above, you'll learn to start treasuring your time alone. And I was a drinker whose later and last stage of drinking was all about me being alone - my wife and kids, my friends, my job - I did whatever I could to find alone time to feed my demons.
What I came to realize is that I was never fully alone - I was with myself, my soul, psyche, whatever term best suits. I was there with my Self and the poison, killing my aspirations, hurting my health, wasting my life. And finally not wanting that, not being able to deal anymore with the pain, panic and suffering I was causing my Self, made me stop drinking when I was alone. Might not be pc, but I manned up, righted my ship. Now that alone time, with my Self, is full of wonder, peace and opportunity.
Thanks for the honest and thoughtful post. Stay strong, it's worth it.
