Messages Can't completely send

I'm having a problem EVERY SINGLE DAY NOW where I am trying to message people and then for anywhere from 5 minutes to a few hours it will completely stop working. I hit send, the "sending" bar loads up to 90% (slowly) and then stops dead and doesn't move. It stays at that 90% mark until it either starts working, many minutes later, until I delete the message, until it goes to "sending failed" or whatever it says with the little red "!", or until I stab my ipod with a knife and run it over with a truck, something I've been tempted to do a few times daily for a week now.

Any help at all would be appreciated, I'm very tempted to quit using messages completely, if my ipod can manage to survive until I do so. I may break it first. For fun
