Living Dilemma

What to do what to do.

Is it better to pay more than half a monthly income to live alone with the peace and freedom of being flatmate free, but in a dodgy building in a semi-economically depressed area, or is it better to save a boatload of cash and move to a better neighborhood closer to central London but have flatmates, no quiet, no peace. Pros, cons, pros, cons....I really don't know. I've been broken into, I'm not super comfortable in my flat given the circumstances around the break-in, but still, I'm 36 and love the quiet and solitude of living alone. Will it be impossible to save my quality of life with flatmates and more cash to spend on seeing the rest of the world???

My building,and a prety park about six blocks away. Sure, I wouldn't walk there alone at night, but where in London would I? Exactly.
