What Causes Numbness In Body Along With Panic Attack While On Clonazepam?

Hello, I take clonazepam .5 mg 2x per day. Tonight I had a very severe situation were I felt paralyzed and could not wake up my husband for quite some time (30 min) by eventually being able to slightly moan. I had the sensation of being tossed around and out of control without the ability to speak or move on my own. I hyperventilated and was very frightened. I take clonazepam for severe restless leg syndrome and many more meds...Would fatigue have a factor?
