Another vote for Yak Trax - I bought a pair last year & will probably be (unfortunately) trotting them out again this year! I didn't find them difficult to put on/off, etc.
I have two principal fears - one is sort of a fear of heights, but in a qualified way. I actually
like being up high places as long as I am reasonably confident of not falling off whatever it is - like there is a barrier or a rail or something to keep me from falling from a height. So ferris wheels & skyscrapers, the Eiffel Tower, many many things like those examples are all A-ok! Narrow path along the side of a hill or mountain with a steep dropoff - not okay, sends me into a panic attack. I have had this qualified fear of heights for as early as I can remember, because I had it when I was five years old in the Colorado mountains & I was climbing up a trail from the Cottonwood Pass (elev 12,126 feet) with my brothers. And like a big fool, I still go hiking with DH sometimes in areas that put me into situations where I encounter this (narrow paths, steep dropoffs, etc) - so I really do try to confront it...usually I have to have DH in front of me, coaching me along, and me not looking down.

And (like I think someone else mentioned this fear already?) - I have a big fear of falling, just generally. I think this stems from that my mother had a neurological condition with which she fell down & hurt herself all the time - and I was still young when she got it, so I was constantly witnessing the trauma & the injuries, etc that ensued from her falls. Toward the end of her life, it was determined (via MRI) that she had considerable brain injury from the accumulation of falls she had sustained over the course of 30+ years.
I also have a thing about spiders too but this has been tempering somewhat since knowing DH because he loves them so much, and knowing that they are helpful creatures - eating other less desirable pests, etc. I freak out less now when I see one unless it completely takes me by surprise - like when it's super-huge and suddenly races out onto the living room floor when the nights start drawing in. If I'm by myself, I have been known to squish them.

If DH is here, we 'rehome' them outside, although he maintains they are house spiders & we are rendering them homeless.

They can be really pretty & I enjoy seeing a spiderweb
outside all covered with dew, that sort of thing.
