Eyelid problem. Muscles contractions.

Hi im having an eyelid problem since 2018 sept. My eyelid is twitching and gets spasms. I have gone through 2 MRI Scans and orbit CT scan but all the reports are normal. I have taken botox four times since this happened. But it doesnt works. Unlike the blepharospasm my eyelids don't blinks frequently but my eyelid muscles are stiff all the time like im squeezing the muscles. Along with that orbital muscles also squeezes with it. Im very much disturbed because of this i cant perform my daily task or any activity. I have met more than 40 doctors till date which includes MD,  ophthalmologists, neuro physicians, plastic surgeons, oculoplasty surgeons, psychiatrist etc. I have tried many eye drops. But nothing works. Im taking anxiety medications as per the prescription of my psychiatrist. My muscle contractions are getting worse day by day my eyes are so much tired even after getting good sleep. please tell me the best treatment for my eyelid muscles contractions.
