A word of caution:
Don't act like a hero because you are lonely.
You may be surprised. Self-pity is a subtle form of pride. Proud people glory in their achievements while people who self-pity glory in their sufferings.
It is really dangerous to dwell too long in loneliness because we are created to have relationships with one another.
It is a strong part of human nature that cannot be erased. If you grew up living alone in a jungle, you will most probably interact with animals or plants and talk to them in your own language.
His disease spread to other 'survivors'.
This should motivate you enough to take action. Don't wait, do it NOW!
Here is an interesting quote:
Loneliness was the first thing that God's eye named not good.
- John Milton
