First off, my heart goes out to you and your countrymen in today's events. I think pretty much every bbs I hang out on has good policies about NOT discussing hot topics like politics and religion so even if this place doesn't I'll honor that unspoken policy and leave out the political commentary. Your nation and it's citizens have already displayed to the world what courage, dignity, and resolve they have when faced with constant bombings in WWII. I know the heart of the British people will survive this and move forward seeking justice. My prayers are most certainly extended to those victims and their families. By your post here, I assume you are alright and that's an answer to prayer too.
Now, guitars.
Strings are the #1 tone shaping element of the acoustic guitar. I'm going to suggest you obtain a set of Silk and Steel strings, also called Folk strings. These produce a very mellow and soft tone, which might not be your goal, but they do use a silk core as opposed to a steel core on the wound strings and tune up with less tension making them more supple and easier to fret. That means your fingers won't hurt as much.
