bad bad feeling

have you ever feel weird or like something bad is going to happen? because i'm feeling one right now, this really weird awkward feeling, feels like my stomach's being twisted juz cause this really really bad weird feeling, I hope nothing bad is going to happen today, but who knows what the future holds anyway, all i could do is just pray and be prepared, i honestly seriously hate this feeling, i just wish that it would go away soon! :(
