How do you keep going?

I don't know.

What's the alternative?

What causes some people to give up, and others to keep going?

I have thought about giving up on life.

But it didn't work. Just heart palpitations, liver damage and a very large dose of embarassment and shame at taking up doctors' time.

However.

I do find more and more as I go through life that the people who really really make the most of life are the ones who have been through pretty dark times.

At some point a decision is made where you have had enough. So you just decide to get on with things.

Best decision ever.
