Unnecessary?

Sometimes there is no reason, cos I have no idea what I'm feeling..
Its like there's nothing big or serious or anything, just that it doesn't feel good.
Or maybe instinctively I know that there's something wrong,
deep down there is something I can't tolerate, there is a line somewhere even I myself am unaware of...

And then maybe I'm afraid, that one day this might eventually lead to something worse...

Unnecessary? I don't know, can't be helped...
