OK, so I asked EnderIte for some random thoughts, and she gave me some, so...

Why do we have feelings? I mean, a lot of people think in their heads, I wish I didn't have feelings, when they get bullied or something. So, why do we have them to begin with?

Well, my guess, is that we evolved to have feelings to survive. Like, fear, that's something that is an emotion, and we have it so we don't get injured or die. And we evolved love because we needed to survive, not just individually, but as a species. So now we procreate because of love. And sometimes that feeling gets hurt, and I'm sure there are reasons for us having other feelings, or, in some cases, lack thereof.

And that's why we have feelings. Well, that's my theory.
