I honestly think only you can answer the question if it's an emergency or not. For me, it's not an emergency until I start REALLY dwelling on suicidal thoughts (I've attempted before). When that happens I make emergency appointments with my psychiatrist and counselor. If you normally don't have suicidal thoughts and suddenly do, I think that would constitute an emergency. For me, feeling bad isn't an emergency, as I feel bad a lot. But that may be different for you. So again, I think only you can decide if it's an emergency or not.
