Haha, thanks Bob. I hear you.
Thanks for the responses. I'm not so much worried about the culture shock. I've spent 6 of the past 12 months in Central America and have seemed to be okay.
I think I will get back to what helped me in Chicago over the winter - get a wall calendar, and start listing off things I did that day. Be active. Go to the park, go to the coffee shops. Engage in conversations. Don't push myself. Enjoy my surroundings. Keep it simple. Develop a routine. Keep learning. Avoid triggers. Heck, maybe I'll even go to a damn AA meeting.
For this upcoming set of planes, trains, and automobiles, I will need to be well rested. So I will get a lot of rest over the next 24 hours or so. Stay away from too much caffeine and nicotine. Breathe, relax. Download some soothing podcasts. Eat healthy.
Just writing this all down and sharing it has helped. Thanks hombres y mujeres.
