I think one of the best remedies for coping is not to get too engrosed in the constant media coverage. If you have to watch the news, just limit it, to say the ITN bulletin at 6.30pm. Newspapers can affect moods too.
I think Social Media isn't great either, although that's me being biased about Facebook and Instagram which I hate with a passion.
As someone said, go to bed at a decent time and switch your mobile phone off from any distractions. Sleeping helps to rest your body and relieve stresses and anxieties, so this is beneficial to the overall state of mind.
Alcohol isn't great for low moods - avoid binge drinking in the house. If you do drink - do it modestly about twice a week. Look at the 10pm licencing restrictions as a bonus to not staying out late and ruining the day after.
Reading novels is a good way of escapism - try to avoid reading anything a bit too unsettling like true crime books.
There is not a lot of choice on the box at present apart from the odd drama, and I hate soaps and crap like Strictly Come Dancing. Maybe get into a TV series on Netflix or buy the DVD box set. I've got into watching some retro programmes like Minder and The Equalizer, which are decent entertainment and takes your mind off things. Avoid the Walking Dead - that is pretty obvious why!
Try and just spend some time out doors - go for a random drive out, even its just for an hour. I live in the North West, so there are plenty of canal walks, or beauty spots to visit. Avoid places like the Trafford Centre or Cheshire Oaks.
Even though the Winter is drawing in - try and make best of the daylight, particularly on a dry decent day.
