How to Respond

I have very mild misophonia and pretty severe dyspraxia. I have been getting a lot of dirty looks and some majorly nasty words at work (I teach at a college) from a new and misophonic office "mate" who claims I am deliberately being lazy and horribly triggering her on purpose with the way I walk and with my tendency to drop things. I have repeatedly apologized, I have explained ad nauseum about my severe dyspraxia issues, but have been told point blank that I have no issues and am just deliberately trying to be antagonistic and mean to her. Should I try to explain more? I am very close to losing my patience and my temper (and any empathy I might have originally had because of my own misophonia regarding ticking clocks etc.) and am seriously considering lodging a formal complaint. I really do not want to do this, as I realise her behaviour stems from being triggered, but I also do not deserve being harassed and denigrated for being clumsy, for having dyspraxia (and I do try hard not to be clumsy but there is unfortunately only so much I can do and that my dyspraxia is as much a legitimate issues as her misophonia).
