I have "loose" structure in my life. Weekdays I sleep 9-6 and work 7-5or 6.
Monday and Tuesdays are my free evenings--I choose to do whatever--meet a friend for dinner or mow or such.
Wed and Friday I go out with my boyfriend.
Thursday is therapy after work.
Sat AM I drink coffee and goof off. I work 12-6 or 8 depending on work.
Sunday AM I drink coffee and do laundry. Then I go to my art studio for the day. Sometime Sunday evening I call my mom.

Of course all this is changing because this quarter I am taking a graduate course, so Tuesdays are now school, the art studio is now study time--every free moment I have is pretty much study time. It is difficult to have the disruption in my "structured" life- I have been on this schedule for many years. But, it is only for one quarter. Things will get back to normal soon.

I agree with your pdoc--structure does seem to help me get things accomplished and calms my anxiety. At times, when I was depressed, I had to set a schedule for every hour of every day or I would sit around and do nothing. Now, I give myself more freedom to decide when to do things--as long as I get things done.
