Not Depressed Anymore...What?

So I haven't been feeling depressed at all recently. In fact, I've been getting along really nicely with my family. I don't really know if it's worth it to be mad at them anymore. They've been nothing but nice to me lately, and the only episode of "abuse" was quite a while ago. Holding grudges is completely out of character for me. I don't hold grudges or drag things out like this. And my hatred for them is only hurting me, not them. It's not changing their behavior but it's making my college experience a whole hell of a lot more miserable. So I guess I'm done. I'm a lover, not a fighter.

Just Wondering

For any Christian that happens to stumble upon my blog:
How does Jesus dying save us from sin? Did people, before Jesus lived, go to heaven? Because Christianity didn't exist then. What if you don't want to be saved like that? Isn't it a little presumptuous to assume that everyone wants that kind of gift?
