It sounds like this bible study is a pretty destructive force in your life. Why do you continue it?
I was at an assembly some years ago when I had the mother of all panic attacks. It was brought on by some guilt trip from the platform. The sister I was with didn't know what to do so she took me to first aid. They had no idea what to do and sat me in a chair and just stared at me like I was crazy. It didn't help the situation, and made it worse. The sister that I rode with had to take me straight home, so she didn't get to do the after assembly dinner thing. Her resentment was very evident. More guilt, more crying. I actually have a picture of myself that day after the attack. My face is red and my eyes were swollen. My hair was a mess.
Don't let her pull that first aid crap on you. I think there was a time when it was manned by people with medical knowledge. Now because of lawsuits, they are simply an area with a sign. There is no help there. And trust me, if you get really sick and need to go home, that sister will resent you for years.
