Basically, I didn't sleep well at all last night, not even sure I got 3 hours of sleep due to some stomach issues. I got out of bed at 5am and still feel pretty shitty. My family and I are on vacation only 2 & a half hours from our home. I said I wanted to go home and lay in my own bed (as one wants when feeling sick). My mother jumped down my throat and told me I was not aloud to leave and to not even think about mentioning it to the rest of my family. I know my grandparents would be okay with it as they believe me when I say I'm sick. My parents however think I fake it to get out of things. Mind you, I'm 21 years old and about to graduate college, I should be able to go home if I truly don't feel well. But my mother is making it a huge deal when it doesn't need to be. I don't feel well, I want to go home, it should be as simple as that but she always makes me feel like I'm a problem when it comes to these situations. Am I the asshole?

Update: My grandmother didn’t feel well either so they asked if she wanted to go home and she said yes so I am now driving her and myself back home. guess it took someone else not feeling well for them to let me go
