How can I get the courage to apply for a job?

How can I get the courage to apply for a job? Im 17 and still haven't had a job yet. If I could I would. But, I have anxiety, mostly about seeing people I know or having to describe things/talk to strangers for long periods of time. I also stutter frequently, and don't know what to do about it. I feel so limited. It makes me very depressed. I feel like people will judge my mental capabilities based on my stutter. And I feel like I'll never live a normal life. I just don't feel like I can do it, I know for a fact I couldn't have a job where I talk on the phone or where I have to talk to costumers a lot. Like I'll never be successful, because I literally can't.
