well how about waiting, until the door gets closed?
don't get all maudlin, and then find out, most or all your tools are still there.
not telling you how to live, or what to think.
but, why be glum, any longer than necessary? There's plenty of time for that. Right now, positive thoughts, and the positive hopes we all send you, can do more to influence things, IMHO.
There's much to be said, in the ethereal realm, about positive thinking and thought, and how it can materialize and manifest......
hang on pal.
