I guess Spillover is the same as Projected stress. Stress from one area of life is being "ignored" and removed to another area where it is easier to deal with. Problems at home may be so big, it's impossible to see where to start or how to resolve them, so they're taken to another place, like work. Once there, almost anything can happen to it... quite often it will expand like filler foam to take over your life. Then of course, you can't see the original problem at home or wherever, and it's like it's been dealt with. All your energy and intellect go into solving the alternative problem and reducing the stress involved in that. There is a feeling of satisfaction if it's sorted, and that gets projected back home, to the original problem. You think that once one is solved, the others are also sorted.
Think again.
I've been stressing out about something at work, and yes, there was a problem with a bullying manager. He's gone, the problem has gone but there is no resolution. Why? Because the original problem wasn't him. Now I know this, (Thanks Morty!) I can see about sorting the rest of it out. You think you have one major problem in your life? Take another look. Deal with them one at a time if you can, but deal with all of them sooner rather than later!
And as for Seasonal stress? Trees - I spent ages driving round looking for a pot grown tree. Had an artificial tree last year and it just didn't feel right. Got myself a beautiful pot grown, lush green, slightly strange looking tree that will hopefully stay with us for a few years. In winter it's a big potted plant, in summer it will be a gorgeous addition to the garden. Provided the cats don't crap in it.
Cards - I've made my own for several years now, it's been easier these last 3 since we got the scanner, but I used to paint/sew/print (potato variety) or collage my own or get Bratling to help. She loves seeing her cards in print, we have a unique card to send out and a record of how well her interpretation of Christmas trees is developing!
Merry Christmas all.... ask Santa for an hour to yourself each day. It's the best thing some of us could ever wish for.
