I'm so sorry for your loss, blackbetty. Even I couldn't help crying a bit over this thread. I hope the mourning passes soon for you.
As I keep mentioning in other posts, I lost a beardie last year and it possibly could've been prevented. I think the strangest thing for me was that throughout most of the 6 months I had her, I kept having dreams related to her being weak, getting injured, being an aquatic lizard, or just water in general. When she finally did pass, the only way I saw to "bury" her in an apartment complex was to send her down the river. Of course, the instant we did so I realized that all my dreams were symbolic and, infact, were in direct relation to her fate.
I don't know if you've ever had anything like that happen, but dreams might mean a lot more than you think if you have chameleon or pet dreams. I've been very paranoid about my chameleon (only my second reptile), but thus far the few times I've dreamed about him it's always been about disorganization with crickets or him growing to be HUGE -- which I think is a good thing.

I haven't figured out what the cricket thing means yet...
Anyway, my point is that dreams and subconscious urgings might also be a sign that something is wrong with your pet. I just thought I'd share in case it's helpful, or maybe just interesting.
Again, best of luck to you. Hope Ben lives with you for a long time.
