Welcome, Yinzer, your post was pretty profound to me. I have always had that exact sense. For years I didn't wear contacts because of some apocalyptic fear that I wouldn't be able to function in life if I had to worry about contact lens solution. . . glasses are more practical, right? I still had some armageddon scenario in my head that has affected relationships and personal habits. And eyewear. I can garden, bake bread from scratch and have a good supply of non perishables, but not much in material goods. Its weird and I know where it comes from. Plugging in dates for next years calendar still feels kind of odd to me and I am DECADES out of the borg. From birth I had it instilled that I would not even get my PERIOD in "this old system of things". I sure didn't worry about keepsakes for my grandchildren! I am really unsentimental and hold on to very little, take few pictures. . . I think I have mimimalized my life and my family's life because of it. I did give them holidays and I didn't take them to meetings, but I really had a shortsighted way of seeing the world. Still do.
You are young and recognize this. If your therapy is good for anything, it should be that it helps you get past this and change the things you want to change in your life and your world view. I hope it is something that is action and progression oriented, rather than just a lot of navel gazing:) I see that you are physically out, but mentally, you are still in. I hope you find a way out of the tower. Grow your hair?
