I kinda know how you feel...
A few years ago I was always eager to ride and always wanted to ride... then after my uncle died two years ago, I was depressed and barely rode for almost nine months... my friends had to literally forcibly drag my out to catch the horses, and I wasn't the best company either.
I finally got to the point of really questioning why I wanted to keep riding when my uncle was no longer alive (he was my 'horsey family member' who I could talk to about anything... we could talk horses for hours and stay on one subject without losing interest). I was seriously thinking about selling both my horses and completely quitting...
Anyway, I was walking down the road and my horses ran down to the fence nickering at me as if they were saying 'hey' (it put me in tears, them running down to me... I was that upset)... I hadn't been planning on riding, but when they did that, I figured I'd take my mare out for a trail ride and think everything over.
So, we went out for a ride and I pretty much just completely re-evaluated evrything... in the end, I realized that I could remember my uncle by riding, not by quitting (if I had quit, he'd be so mad at me), so I decidedto keep riding. I'm glad I did, too... there's no better grief counselor than a horse. It's still hard at times, but I always have my horses.
I admit, now I don't ride near as much as I used to, but I do ride at least twice a week.
Just had to share my story! It's not the same situation, but the basic principles are there.
