Humiliation

I've under a lot of stress lately, mostly caused by the aftermath of the operation and worrying about exams. For those who don't know, after the operation, I spent a large amount of time knew bed, drugged up on pain medication and in no mood to revise. I'm partially regretting this now, in the sense that I really regret not being able to revise but I don't regret the pain meds in the slightest, because although I've stopped taking them on regular doses and just have them when I need them now, I'm still in quite a bit of pain sometimes, so yes, I really did need the pain medication. The inability to revise during that time was not something I'd previously anticipated. It's not just revising that I'm finding difficult even now, I'm struggling to speak coherent sentences or get my point across in any way shape or form, just in my day to day life. This really genuinely worries me, because for one thing I have exams all through the next month, but the most immediate one is this Friday, a French speaking exam which I've had far longer than anyone else to practice for, and yet I haven't been able to until these past few days. Obviously I attempted the revision, and I actually made some quite good notes and got a good start the evening before the operation, but now I'm starting to panic because although I think that I know the first few paragraphs, ish, I'm completely lost after that, and I still have to write my cuecard tomorrow.
I'm going to attempt to ignore the raging winds  outside now and try to sleep. I have a hospital appointment for my wrist first thing in the morning so I'm missing the first few hours of school, but unfortunately I don't get to choose my appointment time.
