How do you accept and adjust to rude and judgemental angry unfriendly DFW folks?

So I am wondering how people who move here adjust to the rude and unfriendly residents who live in DFW. I sadly hate to have to say this, but Dallas is one of the few cities more unfriendly than Miami and DC. This is one of those areas where when you travel outside the metroplex in your car and in person people are just nicer. For example, when you drive to Houston, the vibes and drivers feel friendlier. Then coming back, people become so rude and start racing with you on I-45. It's hard on me because I have a big kind heart and I'm always taken advantage of and bullied in public. I've started becoming rude myself because it seems like that's how you get things done around here. Ive noticed I've started becoming more stressed and angry. It's exactly like Phoenix in some ways. I can't afford to move right now and am probably gonna be here until my finances and credit are fixed. How do people adjust? Not sure if I can get an apartment elsewhere with bad credit and everything in collections.
