Does it get better eventually

I mean I know it does, it's maybe more of a rethorical question...

What I really want to know Is, if it is worth it. It is kind of weird, but feeling good doesn't seem like a good thing anymore, I don't know why I keep doing what I do everyday.

I always make up answers in my head to answer, but I want to post here asking anyone who wants to share their insight about it or experiences, as even though I just turned 19, I don't think I really have a grasp on really anything around me.
