Is it normal i don't have a licence?

I just finished school last year, and have not tried for my drivers licence yet. My mother keeps pressuring me to get one and I always tell her I will soon, but I don't.

I have severe anxiety as well as agrophobia, I rarely go outside and when I do I either stay in the car, or on extremely rare occasions do go outside, but this is when it's usually late at night or when there is hardly or no people around.

I feel like that if I did get a drivers licence I would be a danger when driving. I'm scared I'll worry more about people in other cars then the road, and kill someone. I also find it terrifying to be in control of something so large that could easily cause damage or cause death to others.

I don't want to run over someone and go to jail just because I was so nervous by the car beside me that I wasn't concentrating properly.

I've told my mother this, but she says lots of people have anxiety and I shouldn't use it as an excuse. I can't help it however, that's why it's a mental disorder. You can't tell a person with depression to cheer up just because "lots of people have it".

There are many people who are in wheelchairs, but I don't see anyone telling them to stop using it as an excuse to not stand and walk because "lots of people are in wheelchairs".

I know illnesses vary between people, and some may be capable of controlling it, but some have it so severe that it's difficult to control.

I remember a time I had an anxiety attack in a parking lot, I couldn't breathe and I was crying and shaking, and my mother told me to shut up and stop being a bitch. After we got back home I almost killed myself.

So is it normal I'm really scared to get a drivers licence because I might kill someone?
