I'm genuinely concerned that people won't like who I really am if I tell them
What makes you worried about how people think of you?
So what if I'm the next Adolf Hitler and Mao Zedong
Those were terrible people and it's bad to pretend you might be like them.  Find some better role models to aspire to be like!
It's not like I'm trying to become like them. Fuck.
That's great then, no one should legitimately try to have them as their role models. Just be yourself and not stress out on labels too much, and relationships will come naturally since you aren't faking things!
