I'm sorry to hear that you're feeling this way. It's important to address issues of harassment or bullying. Here are a few steps you can take:

1. **Document the Behavior:** Keep records of any messages or interactions that you feel are inappropriate or harmful.
2. **Report the Behavior:** Most platforms have a way to report harassment or bullying. Look for options to report or block the user.
3. **Reach Out for Support:** Talk to friends, family, or a professional who can offer support and advice.
4. **Consider Your Response:** Sometimes, not engaging with the person making fun of you can be the best course of action. Responding can sometimes escalate the situation.

Remember, you deserve to be treated with respect and kindness.
