Do I just want attention???

I was at a school party and sitting at a table with my friends. Most of them know me pretty well but this one guy I didn’t know at all. The topic came up about how I was

“married”.

A fake marriage to 3 of my friends😂(all girls). One of the guys ask me, “so your lesbian.” I tell him the marriage is a joke but I’m actually bisexual. The guy that I barley know turns to be and says well we three wives u should balance it out with a guy. I say actually I like girls more than I do guys He looks almost offended and say, “ wow someone so open about being bisexual must just be doing it for attention”

I struggle with depression and mild anxiety and though I hadn’t thought about this since I came out of the closet I wondered if I was just seeking attention by being open about my sexuality. Please comment ur thoughts.
