please help me

hello, first of all i apologize for my english as it's not my first language.

i am a 21 years female.
i am very desparete and don't know what to do, my homeopath gave me 3 weeks ago a remedy called Staphysagaria 30ch*3, she explained that it should help with anxiety but instead i started to have serious side affects, i can't eat at all and if i try i have the urge to vomit, i developed body tic in all my body, i have total apathy- literally i can't do anything, i become totally numb i can't cry can't laugh, i don't feel any pain- always in my periods i have had terrible pain but this time with the effect of the medicine nothing at all .it is as if i lost all my senses i cant sleep, eat, concentrate feel emotions - nothing. i can't even sleep for the entire 3 weeks, that also is a huge part for me because if could have slept even a bit i hoped i would have felt a bit batter.
i took a pill for sleep but even that has no affect on me,i am just awake all night long.
i rally feel like a robot that isn't capable to do nothing. that is so upsetting because i am very emotional person and now i don't have even a tear in my eye.
the homeopath tried to antidote it with nux vomica, an camphora, but it didn't help me at all. she said also to drink lots of water and coffee , apple cider vinegar.oh she also tried to neutralize the remedy with Staphysagaria 6ch. i don't feel any improvement whatsoever.
the problem that she went to a really long vacation and now i am alone with no clue as to what to do, i am feeling as if i lost my identity and can't recognize myself anymore.
i am really afraid i am going to feel like that forever.

i really appreciate for any kind of advice or whatever you just feel like you could guide me or give some information ,

thank you so very much
