<human>: Can you succinctly summarize the text in 1-3 sentences?

so, literally minutes ago I got caught smoking cigarettes in my university halls in Wales UK. Semi-FU more advice needed.

I had this gut feeling that I should wait to have my cigarette (which is normally smoked in my bathroom) but I ignored it and smoked away. Anyway, on to the FU..

My roommate next door left food unattended in the kitchen and he came up to ask who it is... so, he knocked on my door first and said "Have you been smoking in your room?" So I initially denied it but soon just became silent, he booked me which means I pay a £100 fine... I've been caught once before, and he let it go (I know, I'm a fucking idiot) but I suffer from sever anxiety attacks and I have GAD (Generalized Anxiety Disorder) so Here's where I need the advice, How do I deal with this entire situation and how on earth do I talk to the office about this??
