I had a very similar experience, after 18 months one hive swarmed never to be seen again, one hive just died. I did get some honey though, about 8 jars, turned out to be the most expensive honey in the world. I got stung many times, came up like the Elephant Man, the Fragrant MrsP got stung, the dogs got stung. Frankly I think me and the bees were glad to see the back of each other.
You live and learn. My advice to the OP is do your research, really thoroughly, then walk away.
EDIT. It’s a really expensive hobby.
Thanks for that, I will research it, but I reckon I'm going to give it a go.
