Truth be told, I'm going through the same thing, even with my family members (I have 4 sisters and a sister in law, and even experience envy from my own mom) but the reason they're jealous is because they have low self esteem and feel that you're better than them even tho ur just being you. People envy you and see you as a threat when you seem too perfect. But the way to counteract that is to show some of your weaknesses. Things you don't mind people knowing or seeing, as it shows that you're just as human as they are and they'll start to back off. Also, don't tell people your dreams unless the person you're telling has already accomplished what you want because instead of envy you, they're more likely to provide mentoring and aide you in accomplishing your goals. Also, try to find more people who you can relate to by joining groups that are focused around your interest.
