Welcome to the site.
I am sorry to learn about your struggle with tic disorder and i empathize with you.
Well, yes there are effective medications available for managing tics and no, the doctor aka a psychiatrist or neurologist whosoever may start you on these medications after evaluation would not put you in the category of mental insane, so kindly relax nerves and do not jump to hasty conclusions.
You see tics are not uncommon and therefore the treatment is readily available nowadays, you should have sought for the same much before so that your tics would not have become as severe and frequent as they are now.
So, i am mentioning below some of the medications that you shall discuss with your doctor, preferably a psychiatrist or neurologist as they will be most suited for treating such a condition.
1) Tetrabenazine at dose of 12.5-25 mg once a day at bedtime which needs to be slowly titrated to three times a day dosing eventually. It is not to be used if you have a history of liver impairment.
2) Olanzapine ( zyprexa ) at dose of 5-10 mg / day or quetiapine ( seroquel ) at dose of 25 mg / day, these two are neuroleptics which are found to be very effective in tic disorder.
3) Clonazepam ( klonopin ) at dose of 0.25-0.5 mg twice a day.
You shall discuss all of these with your treating doctor, a combination of 1 & 2 or 2 & 3 may be preferred by the doctor over single drug regime for getting quicker and more effective response.
I hope this helps. Kindly do the needful and hopefully your tics will get control and make your life easier than ever before.
Wish you all the best.
