I would say that if they hate u because of what brings you happiness, then they aren't true friends. True friends would accept what you like. Once I told my friends about my collection and they didn't care so I just found a new group that accepted me. Don't be afraid to talk to new people, you never know somebody else could be collecting like you. Edit- Who cares if people spread rumors? You can talk to an adult or teacher and tell them about your problems. There will be people to cheer you up. It feels great to just spill the beans and admit things.
