I don't know the specifics of what people did to you.
But I feel compelled to share I slightly different viewpoint of 'making fun of' that I have come to develop over the years.
I think people making fun of other people is actually really beneficial and is a natural dynamic of human social interaction.
People will nitpick at each other in attempts to homogenize and refine each other, this is really the purpose of making fun.
When your younger in grade school, or even high school, this instinct manifests it as being very mean, especially to us. Because we typically get made fun of for things we will never be able to change, and the people making fun of don't realize we can't change that. I was poked fun at alot in my early years, and I thought this was very horrible. But I came to realize these people aren't inherently mean, they are expressing a innate tribal instinct in humans, that humans placed in proximity of each other will nitpick, they poke fun, it is a tribal dynamic, to get everyone on the same wavelength. People will naturally try to 'make fun of' or 'nitpick' things out of you that don't fit into the tribal dynamic of the group.
Typically more serious poking fun of is done by groups of people to individuals. Because the group is literally trying to erode incompatible properties out of the individual so they can join the group. So if you understand poking fun of in this manner, to me I stopped seeing it as so terrible. You have to understand that even people who highly respect each, even people in tight knit groups, still heavily poke fun at each other, for this reason, of trying to homogenize themselves to form a stronger bond. The act of poking fun is not inherently mean, it is inherently for strengthening social bonds.
However, the thing that is terrible about this for us is that, many of the qualities people try to erode out of us, cannot be eroded out of us by nitpicking, and we ourselves don't even realize that. And us being 'weird' we have many qualities people think they need to erode out of us.
However there is a solution. Eventually people stopped poking fun at me about my oddities when I started to unapologetically express my oddities. When I started to very sternly declare, I am weird, this is how I am, this is what I am going to do. If someone poked fun at me, I expressed my weirdness more intensely. Until I stood my ground in my identity and my weirdness, then people would realize, its not a quality they can erode out of me, and they would respect it, even find amusement in it.
If someone says something purposely on the meaner side to me, I return it to them. Really you must learn to be quick in your thoughts and how you respond to people. It is more a social test than anything. I have actually gotten really good at this and have became friends with people who, 10 years ago, I never would of imagined myself becoming friends with. The truth is, everyone wants to be friends with everyone, some people just have stricter and more mean fronts to get through. You might find being outright bullyish back to people of those types is actually what they want, its how they play, its how they flirt with others. In fact I would go so far as to say, you should be slightly cold to everyone you first meet, make them earn your respect.
