This is a very selfless way of living, and for that you have my respect. But the chief cause of loneliness for many people is the fear that the person they were waiting for will never come:

There is a fire which burns inside me, but no-one stays 'round long enough to warm themselves.

Knowing this, if you can truly remain steadfast in your positive outlook on life, then you have achieved true strength. Hard to do in an oversocialized world.
