AITA for pulling out a glock 17 on my teacher because she said “I don’t know , can you?”

I know the title may sound like a little bit of an overreaction , but hear me out . She had been saying it all the time I asked her if I could go to the toilet , and I was tired and a little annoyed by it .

Today was the last straw , I really needed to pee badly so I went to ask her if I can go to the toilet , "I don't know, can you?" she replied with a smug look . I had finally had enough and pulled out my glock 17 from my left pocket , loaded the magazine , and shot in her direction 4 times . I made sure the bullets didn't actually hit her because I knew I should be the bigger man and control myself .

She suffered cardiac arrest and a little bit of hearing impairment due to this , she's doing alright in the hospital now . I was sent the therapy because i was "overreacting" and what not , the therapist told me that I really was overreacting and that I'm a "psychopath" , it infuriated me and I pulled out my glock 17 from my left pocket again and pointed it at him , but I decided to be the bigger man and control myself and not shoot him , he immediately shut up and let me go .

So tell me reddit , was I really "overreacting" by (rightfully) pulling out my glock 17 in these two situations ? I personally think my actions were justified . AITA ?
