hi everyone: a wee update - thought I'd mention that a few times during my 1-hr. walks I have felt the odd old feeling of "wish I were home already". When this happens, I slow down, look around and appreciate the great outdoors, the trees, the river (I live near a beach) and remind myself of how lucky I am to be able to go out and enjoy all this - and I look at my dog and she is having such a great time too. Then, things seem to fall into place, I continue and it is all o.k. and I am proud of myself for not giving up or giving in to these negative thoughts. So, I guess what I am trying to say here, keep up the positive self-talk, the positive thinking. It works!
