You have the right to be uncomfortable and you definitely have the right to not want to go. And it's ok to be weirded out by it at first. But you really need to learn to accept your mom for who she is. But you definitely have the right to be uncomfortable and you shouldn't have to go. Just have a talk with your mom and tell her that you don't want to go cause you feel it would be awkward or you could always lie and tell her a different reason but that is a last resort type thing. Hope this helps.

You definitely have the right to. Don't let your mom get you down. It's your life not hers. She doesn't have the right to yell at you for feeling uncomfortable, and whatever you do just no you are not obligated at all to go on this trip, and if your mom is hard-headed (sorry don't want to insult her but couldn't think of any other word) then you pretty much have no choice and kinda gotta lie. Or just tell her its too soon if she is a good mother she will understand.
