Ooh, I gotcha. My boyfriend is the same way with how he handles stress, which creates more stress. Just know there is a nice vacation coming up, and you'll get through it alright. College was like that for everyone, especially near senior year. Of course, the reasons vary. But, you'll make it. :D It's a good thing to care about your parents and their situations, but I guess also keep in mind that they're adults and have been handling their problems for a long while. That's what I have to tell myself about my mom, because I was the same way - caring way too much becomes debilitating. Not saying that's your problem or trying to give you that non-partial, over-involved stranger advice. I've just been there and even though I know just hearing wouldn't really fix it, it would've been good to know someone else went through the same thing. Anxiety makes people tend to feel alone, when really lots of people understand but just don't know what's going on in each others' heads so they don't pick up on it.
Anywho, I'll do that - would you like for him to be in line to get food or sitting down? Do you want his friend with him or moved off temporarily - as in, going to sit while Aiden is still in line?
