Feeling a little discouraged

I have been working my butt off at the gym...even have been attending a turbo kick class....and for me at my size is still a challenge...but I move continually even if I can't do all the moves....but my weight is at a standstill and I weighed for the first time since August...the measurements are about the same....HOW CAN THAT BE????? My clothes are falling off...

I have not felt this down the whole time...it has hit me hard tonight...and I am tired of crying about it.
