My Mistake, I Wasn't Saying Anything Actually

As expected, I din really enjoy the evening. The glass of white wine that I had was probably the best part of the evening. I spent most of the time listening; I onli spoke when probed. I was simply too engrossed in trying to comprehend wat was said than to think of wat to say. Were they mumbling becos they had too much drink or was there sth wrong with me? I don seem to have any great problem in understanding them for the last few weeks or so...but why am I struggling yesterday? Or was I jus freaking myself out too much?...I’m feeling so demoralised. I just lost a battle that I have been preparing for. I think it’ll take a while before I recover all the confidence I have lost.
