I grew up in Navajo County(Holbrook & Snowflake) and now live in Downtown Palo Alto. I understand the drastic change you've experienced more than anyone on HN. These Ivy league pricks have no idea. No matter what you do...don't give up. Learn as much as you can and keep growing. I went to ASU and when I was your age I went through a similar experience. All you can do is keep innovating, keep learning and find a support structure. AZ is not known for that...not even in Phoenix. Get out of Tuba City or wherever you are. The rez is not for driven people. I have some Navajo friends in SV if you need help. Reach out...there are always options.
