i'm just a shit that deserve my place in the toilet bowl

Yesterday was just not my day as i did badly for my language teaching presentation and sociolinguistic presentation. After my language teaching presentation, i kept on asking myself maybe teaching is just not my cup of tea. I'm very enthusiastic in involving myself in education line and treat it as my lifetime career but after yesterday i suddenly thought that maybe i'm just a piece of useless shit that won't be able to do well in anything. Maybe i'm just destined to be a rubbish collector which nobody will want to do in today's world. i'm just a piece of shit that also make others feel dissapointed. I really feel very depressed yesterday and actually my tears were in my eye just that i don allow it to fall.undeniable, i'm really an useless shit that just wasting food and money.i'm useless.i can't do anything.
when i thought that the situation will be better for socio presentation, who knows actually it was the worst. I totally collapsed without any doubt. Again, my tears appear in my eyes again but it was in the middle of the presentation, i can't let my tears drop down from my eyes.Luckily, my tears listened to my desire and didn't fall down from my eyes. During these 2 years, yesterday was the 1st time i had such feeling .I hope that that will be the first and the last time this kind of feeling will never appear again.
