Wrecked I sort of know what your're going trough. My entire family don't support my choice of doing LL in the future. I literally don't have any good relationship espically with my parents anymore, because they keep trying to talk me out of doing it. My parents are wealthy and could easily support me financially, but have chosen not to do so, even tho I just need the last like 20% of the money.
At the end of the day if someone don't support you doing LL, that just tells you that they're bad at putting themselves in others shoes and unemphathic, and because of this should avoid them. It's better not to have toxic people in your life than try to change them, they're never going to be different.
Honestly I think everyone has something that is bad trait. Wether it's being short, having a big nose, being fat, bad style, bald etc people can always find something to bully you on. However they're usually only going to continue the bullying if you keep giving the right reaction by being mad or annoyed or seem like a easy victim and fall into there cards. Never give people that option, just simply ignore them like they don't exist.
But I guess wearing loser pants, (regular/slim?) not drawing unwanted attention towards it, and working on the things I listed before would greatly improve this aspect of your life. It did for me at least.
