To live is to suffer but to survive Well, that's to find meaning in the suffering. Thought? ?

If there was only pleasure- pleasure would have no meaning. Left and right define one another. Try and explain 'wet' to a fish. Like this.

People that become addicts have unbalanced their equilibrium. Attempting to chase an earlier experience that cannot be recaptured.

The answer? Stop, and if it is really, absolutely, vitally important that it is recaptured? Wait a predetermined amount of time and try again.

There is a condition where people cannot feel pain- imagine; accidentally cutting a hand while preparing food and only noticing it when your palm/leg or whatever becomes wet...

To live is to suffer, to survive is to find some meaning in the suffering. — Friedrich Nietzsche.

There is no meaning in suffering as far as I'm concerned.  It's better to avoid it or reduce it rather than wallow in it.  Likewise life doesn't have to have a purpose, it just is.  If you want a purpose, you have to invent your own.

Living through something or a tradegy.

No. There is no meaning in suffering. It is best to forget about it and get on with things the best you can. Otherwise you don't escape the past.

Humans are always challenged by struggle. Learning to enjoy the struggle is among the highest of wisdoms. When the struggle is enjoyed, it becomes no longer a struggle you see, it becomes inner growth, character and True learning. Living and suffering have no equivalency, or co-dependency, although at times it may seem otherwise in the physical world. 

life isn't that deep we're all just a bunch of Cherrios in a box waiting to be eaten out

Surviving doesn't require finding meaning. It's just the natural consequence of involuntary breathing and involuntary heart-beating because of one's own autonomic nervous system.
