The best way to get people to stop thinking you’re a “freak” is to spend time with them and show them you’re a nice person. It’s okay if you’re kind of unusual. Everyone is, so try not to worry about it. What you think of as weird traits become charming quirks to people who know you.
Of course, this is much easier said than done. I wish you the best. Just try to remember that nobody judges you as harshly as you judge yourself.
