So they thinks its ok to treat me like this

Just keep your eyes on the prize. I went from the bullied victim in that school to Prom King in the next one. Once you're out of school, you'll meet new people who won't know about your past. At my second high school, nobody knew who I was, much less any issues. When you graduate, you'll get this fresh start.

People are strange creatures. I just ignore them, except when I'm getting paid. When you're in business for yourself, you learn to grow a thick skin. You'll overcome the attitude about appearances, clothing, cars, .... Trust me- clothing and cars don't matter. If somebody can't see you for who you are, they're not worthy of your time.

Do what makes you happy, and life won't be too bad.
