Hmm, your husband is being a bit of an arse, but I can easily see how he might feel that you are just really careless with things.
First, do go get yourself checked out, esp if this is just recent, it may be indicative of a more serious problem.
Second, if things break quickly, take them back to the shop and get them repaired or exchanged under warranty.
And try not to say "it just broke". It makes you sound like my 2 year old! In general, things don't just break in the quantities you are talking about, something happened to make them break.
Eg. Cheap mp3 player for the car and satnav. Are you one of those people (like my mum) who is unable to gently ta buttons or touchscreens, and effectively punch them instead? Could explain why things like this break. So be gentle with things like that.
Lost battery back - sit down at a clear table when taking things apart or doing fiddly things. My mum is always losing stuff like this - its because she invariably does things like this in a really messy location, and then can't see the thing she's looking for.
I downloaded a virus onto it - well, you must have been downloading from some really dodgy sites. Stick to itunes and the like, and get some decent AVS for your PC.
Tap, food processor - are you often in a hurry and just slamming things around? Sounds like it.
Hoover - ditto above, do you tidy up properly before hoovering? Maybe that's where your battery back is?
My mum was really like this - always flustered, in a hurry, in a mess, disorganised and things got broken, lost etc. She'd say, just like you, that she wasn't doing anything to it, it just happened. Thing is, we could all see her jabbing wildly at buttons and remotes etc, so hardly suprising she broke them. She had accidents because she never focussed on things, always thinking about something else. She actually went on a brain train thingy to help, and it had a remarkable effect. Now we have to deal with her wandering around with post-it reminders stapled to herself, but that's a whole other story!
