I haven't got much knowledge regarding practicalities about houses etc I'm afraid but maybe the CAB would be worth talking to if you do get stuck.
It must be a huge shock for you after 4 years so make sure you have time to grieve. Having practical things to sort out is good because it takes your mind off things and gives you something to focus on.
I reccommend the book 'It's Called a Break Up Because it's Broken'. I know a lot of baggers have found it useful over the years.
It may seem awful now but you will get through this and it will make you stronger, honest
