Back pain and crying with frustration

My back.hurts so bad :-( I ask my boyfriend to rub out one of the knots in my lower back so I can walk normally and he starts bitching how I never rub his back... which is a lie, im just not strong enough and he complains everytime I do until i get the stupid vibrating massager and use that on his back(which hurts my already messed up wrists) so i cant walk and my boyfriend is being a jerk and to top.it all off I'm an emotional wreck.today so.i.just start bawling when he.refuses to.rub my back and now he's trying to.act all nice.... but still.wont rub my back :(
