Suicide block is called so because (surprise surprise) it's where Keele people go to jump.
Keele has one of the highest university suicide rates in the UK (alongside STD and rape, supposedly). I think the last suicide was 2 academic years ago. It's not a bad block though, I've had some awesome times in there. Just make sure your legs are working, there's an awful lot of stairs...
Every university has suicides, it's really not much to worry about.
As for sharing rooms... usually you end up better than the rest of us. When a room becomes available for one of you to move out, I'd offer it to your room mate if I were you... if you stay in your room, you get a massive room, and TWO single beds- push them together and... voila! A double bed. Awesome.
