Am I mentally Insane if I try to kill a Man just because he was bothering me which got me angry?

I'm a female high school student. I suffer from Major depression and anxiety problems. I don't and never had any friends. All of my teacher treat me nice when it comes to female ones. I had a total of 5 different male teachers, and two treat me like ****!. One was my Economics teacher and the other one of of my PE teacher Individual sports. Sometimes I get depressed and would not do my work. My female teachers will just tell me what is wrong with with me. They will try to talk to me about my problems, which is why I prefer female teachers. Male teachers don't know **** and will just get mad at me and start yelling at me. Then they will call the security and take me with him. This is why I started to hate male teachers. None of my female teachers never once did that! The other time my PE teacher was bugging me into participating in Softball, but I couldn't because I was feeling sick! All he did was getting pissed off and calling the security. I just wanted to grab that Baseball bat, and swing it straight to his head!
