Welcome back, and congratulations on your retirement, Cheryl! I was off the site for a couple of years myself, and came back earlier in the year when I realized how much I missed everyone here
It does take a while to adjust to being retired (hubs and I both retired in 2011, so I'm pretty well adjusted now!). I know everyone claims to be busier than ever once they retire, but in my case I think it's just that everything takes me twice as long to get done as it used to. For instance - when working in the garden, instead of rushing to get things planted as quickly as possible, I'll put a few plants in and then just take time to enjoy listening to the birds and watching the bees, maybe admiring how large all of the trees that encircle our yard have become... sometimes I think it's a wonder I get anything done at all
Enjoy life - as Henderman said, "The point is to be happy, so do what makes you happy and forget the other stuff. After all, if you wanted to be miserable and stressed you could simply go back to work." I couldn't agree more!
