How do you feel about getting the pity smile?

How do you feel about getting the pity smile? I'm currently in high school. Whenever I talk in my really soft tone and stutter when asking a complex question, I always get the sympathy smile. I can just feel them feeling sorry for me and that makes me feel sick inside. The smile just reminds me of my curse, the restriction that prohibits me from making friends like everybody else, the restriction which makes it so no one takes me seriously. I just hate getting the pity smile, even though I know they are only being supportive. I had a practice presentation today before a really important one for entrepreneurship, and I stuttered. My teacher (who I barely talk to) pulled me aside and asked my if I wanted to do the presentation. Once again, I know she is only trying to help from her POV, but it just made me feel hatred towards myself even more. Why does this wretched condition come upon? The amount of jobs that I know I can never get because of my stutter. Flight attendant, down the drains. Nurse, even if I knew what to say, me stuttering would give the illusion that I had no idea what I was saying and no one would hire me. I'm considering becoming a trucker. You don't have to talk to anyone and the job is in high demand so I won't struggle severely to get the job if I get a CDL. I am taking a bit of time getting my drivers license but I think that a trucker is a good job for me. What do you think? Sorry for ranting right now, but I had to get it off of me.
