Are there LGBT legal aid groups near where you are? It's illegal what they're doing so seeing a lawyer might help. Is there a PFLAG or some other LGBT support organization?
Keep careful documents. Write down specifics. What time did it happen. Who was involved? What did they do? How did you react and how did you feel?
If all else fails, try contacting EEOC, whose job it is to enforce these laws.
Good luck, Jennifer, and all my hugs. No one should have to endure this.
