Up or In?

I can't decide whether I'm giving up, or I'm giving in.

Here are the definitions of both words from the ever-helpful dictionary.com

To give in:
1. to acknowledge defeat; yield.

To give up:
1. To abandon hope; despair.
2. To desist from; announce
3. To surrender; relinquish

While on the surface, they almost look the same, I think the difference comes in the acknowledgment of truth.

To give in looks as if you know you're wrong, and you admit it.
To give up looks as if you know you're right, but you realize there's nothing more you can do.

I think I'm doing a little of both. I'm giving in knowing they've made it longer than I would have ever expected. But I'm giving up knowing this isn't right. I can't believe it's right.

This is stupid. I don't really care about the difference in the phrases. Specifying my correct word choice won't make me feel any better.

I'll still hate that I have to do either one.
