What should I do about my friendship situation?

I avoided befriending the educated people in my church and university because I did not feel comfortable being around people with really high standards but my uneducated friends are so incredibly stupid! On e weighs 350 pounds from eating too much and than wastes all her money on make up and clothes to feel beautiful when she won’t stop gorging on food and actually says no when I tell her to buy nutritious food instead of make up and clothes, another borrowed $10,000 dollars to bribe a guy into dating her when she weighed 300 pounds from eating too much and than her welfare mom and minimum wage dad had to pay off her debt, another one flunked out of three colleges and told me my university degree is worthless but married a rich man by sleeping with him and every time I have an opinion that is different from hers, she gets angry and tells me my opinion is wrong and she’s too stupid for her opinion to be better than mine every time we disagree, and another flunked out of high school and keeps trying to date me and a third guy constantly brags about his disability and than asks you for money and he takes the taxi to McDonald’s because he is too lazy to walk 14 minutes in the summer time to get to the restaurant. I had a lot of smart people try to be my friend too but I rejected them because I did not feel comfortable around them and now all my friends are stupid.
