Just an example, about 12 years ago I got into the sport of dog agility. Now there are people who knew me way back when I was just learning, when I couldn't do a thing. But I was in my 30s at the time. Re-invention is an amazing thing. For the most part, only people who go through a really traumatic event or circumstance experience the process of re-inventing themselves. You get to choose who you'll be, with you you'll be, and who and what you want in your life. You've only had her out of the house a short while. I'd give myself time to breathe and just exist for a year or two and let myself recover while beginning to think of where I might go or what I might do.
