Sorry if this is incoherent. I'm tired and in pain.

My (20M) step sister (24) "Sara" got married on Friday. The timing was good because family could be in town for both the wedding and Easter, which was kind of lumped in with the wedding festivities. Most everyone came into town on Thursday, and so that my step-sister could, quite a few family members were invited to the rehearsal and dinner.

Sara, her dad, and my mom are very big on keeping up a certain image. Not sure if that's actually relevant.

I left the rehearsal before dinner because my middle and lower back were cramping. It wasn't horrible, I could have stayed, but I'm not used to having cramps so I thought maybe I had eaten something bad and wanted to go home just in case.

The wedding was more of the same. I made it through the ceremony and pictures but then left quietly. I was still having some cramps and during pictures I was getting sweaty and queasy.

Sara and our parents did not appreciate this. They told me afterward that everyone was asking about me and it would have been more considerate to tell the whole family that I was leaving.

Yesterday I went to Urgent Care but they didn't find anything wrong.

Our parents hosted Easter. Sara and her now husband came as well (they'll be taking a late honeymoon in the summer). I stayed in my old room all day. Still hurting, still feeling sweaty and queasy if I overextend myself. I'm normally funny and engaging but knew I probably would be so today.

After everyone left they once again berated me, saying I should have sucked it up and I made the whole weekend about my absence. To my knowledge no other family members complained but I imagine they asked where I was.

I tried to say I didn't feel well. They asked if I had a fever, vomiting, if I could stand up straight, loose stools, etc. and I told them no, which seems to have solidified their opinion that I am an AH. "I just don't feel right" isn't acceptable I suppose.

Am I? Should I have sucked it up even for an hour or two?
