"delayed appointment causing me extreme pain"

my appointment was a week ago which I waited few months for it in agony ...1 week before the appointment...the Eastman dental changed it to October cos there moving offices..I called to to explain im in terrible pain. I was told I will have to wait for a whole extra month and nothing can be done...my pain has spread to other parts due to delay..feels like no1 understands..I feel lost even my gp cant speed it up cos its the hospital that should consider speeding it up for delaying cos of an office move.....Clearly im not receiving the care im suppose to I hope others dont go though what im goin through....I cant work I cant eat..I cant stand for long...I cant sleep ..im screaming for HELP: ('
