What do I do if I think my church friends think Im a lesbian?

I think this because they asked me to move out of their room the second night of our trip after a room mixup. (Different hotel) I am so upset, I went on this church trip and it seemed like the whole time I was there people were trying to avoid me and exclude me. They moved when I would sit next to them or they would choose other spots over the one next to me. They also took pictures and tried to move their heads to block me out of the picture and when I saw a picture on FB of a group of people sitting eating lunch and I had been cut off except for my hand. Like they cut me out of the picture. Also I was in a room one night with one group of people but then because of a room mixup where we were double booked in our hotel, we had to switch rooms around. I was the only one out of my room asked to go to another room. Why me?? Do they think Im a lesbian? How on earth would I go about finding out if they think this?
