So, I'm going to be graduating high school soon

. I have an internship at an office where my grandmother works, but I'd like to get a real independent job soon.
The problem comes on at being skittish to a job when I'm genderqueer. I've considered just going by my assigned gender, but that feels so uncomfortable and makes my skin crawl.
Does anyone have any suggestions on finding a job or workplace that would be friendly or welcoming?
On top of all this, I'm very soft spoken with people I'm meeting for the first time. Any ideas?
