end of hoping

But is this only the grip of mere fears and unconfirmed worries?

A coldness seizes and drowns my heart every time I see the way they talk. It is excruciating, and then it begins to numb me. I feel like I'm worrying about something I shouldn't care about. But what can I do but care?

Do I know the feeling of heartbreak? I do not know if this is it, but I think I do.
