Days Like Today

Thoughts flood me. I feel like I'm caught between two spaces, and I know neither the location or purpose of either. My life right now is completely different from everything I want, everything I expected, or anything that I ever thought would make me happy. Yet, I feel as though I have no choice in the matter of my own existence.
I speak when no one wants to listen, and I know that no one wants to listen. I know that no one really cares- but I can't stop. If I stop talking, I might cease to exist. The only thing that keeps me alive is this constant ridicule, and I feel it from everyone. I want constant reassurance, but at the expense of everyone else's sanity. This is how it feels some days. Today.

So my question is, is this worth it? What's the point of existing if I only exist to feel this way?

Does anyone else have days like today?
