My name is jessica and i'm 26. I work for a well-known bank. I have a co-worker that hasn't been fond of me since i started working there. She makes sarcastic remarks from my clothes to what i eat. She recently discovered that i'm a lesbian and met my girlfriend at an after work get together. Since then she's been treating me more horribly and even made remarks about gay people towards me. It's to the point where i don't like going to work in fear of what she's going to say next. What should i do, or what can i do about this issue if there is anything i can?
