ativan withdrawals

im a 16 year old and ive been on 1mg ativan for over a month. almost 2 months. my last dose i took was 18 days ago. of course i tapered but i have no idea if i tapered too fast because i did it without my doctors notice. he gave me the prescription then told me once ive taken it all i should see a counsellor or psychiatrist. so yea i ended up using that last prescription to taper and overall ive been on less than 2 months but im severely worried of having seizures. i havent had terrible withdrawals in fact i barely had any at all. these past 18 days have been easy, except the fact im terrified of having seizures. i havent been alone at all these days because of my fear. i actually started to sleep in my parents room because of it. im always terrified in class and everywhere i go. for about a week ive been seeing colours, but i dont think theyre auras. like its not like theyre there for a long period of time theyre actually there for a couple of seconds but enough for me to notice and get scared. they only started appearing when i got more and more scared of seizures and i been constantly looking up grand mal seizure symptoms, ativan withdrawal and seizures and stuff like that. everyday is just a scary time for me especially when im alone and i just wanted to know if it really is possible to have a seizure when being on a low dose of ativan for this short amount of time and even having a seizure when you dont have all the withdrawal symptoms. i just wanna say again that i did taper a bit from 1mg down to 0.75mg down to 0.5mg amd then after i was forced to jump off from there and i didnt have bad symptoms and the most i had was anxiety. 

I was on 4 a day if not more for 8 months five years ago and I honeslty guess weed to come off it I didnt taper I just stopped and I never had any problems but everyine is different right I do have ativan for timea now if I need it but I dont use it if I dont have to
