The best thing/advice I could give you is - just be yourself, and don't try to get approval of anybody, literally. I'm an ARMY first and then comes all the other groups/solo artists, so I'd always mention BTS first (unless I forget tomention them and sudenly mention other groups before them).
The less you care about their approval and their looks, and the more you care about yourself, your life becomes more joyfull. One more advice from me would be this: in those moments, just turn on the song that you mostly like and listen to it, while enjoying it - and you will forget about them. At the end of the day, your life and thoughts are in your hands, not theirs.
Many many hughs and loves from me
