No personal experience, but it makes sense. Depression can be sapping and the best races need physical and psychological powers to combine... so maybe that puts you at a disadvantage.
Hopefully someone with direct experience will share it with you, but one question would be whether your weight has changed since last year. Depression is quite often accompanied by a weight change (up or down)... but if you've put on 10 or more pounds since last year, then that could explain the entire difference.
On the proxy votes you are right and wrong. I am too late to apply for a proxy vote but eligible for an emergency proxy vote as my work has told me I need to be out of the country since the proxy vote deadline passed.
Well that's good -but really surprises me. What is the proxy-vote deadline for then?!!
Skinny... you say that Jo Cox's murder will seal the referendum (presumably you think it helps Remain). Do you really think so? I suppose it might just lean towards people rallying around the establishment a bit... and in such a tight referendum, even 0.5% shift could make a difference! If there is an influence, I think it will be that small though.
Bad news for you though.. the deadline for registering for proxy votes passed last week. http://www.aboutmyvote.co.uk/how-do-i-vote/voting-by-proxy
