Pre Major Achievement Anxiety or Whatever

So tomorrow im literally fulfilling a lifelong dream right?? Like im so happy about it, i should be, and i should be proud of myself and whatnot- but the only emotion i can feel is just stress, crushing painful in the chest kinda stress. I just have that looming feeling that something will go wrong, that something will ruin my joy and whimsy. Worst of all, i think what will ruin it will be me. The closer the event gets the more i remember, oh wait- i have crippling social anxiety and voice dysphoria!! uh oh!! i'm a transgender kid!!! 

But, at the same time, everyone that goes to this event is always super kind and chill and everything, but also also- im gonna die!!!! I need to have my riddles on lockdown!!! oh my god!!!!! what if someone tells me a riddle back and i dont get it?? oh my god new fear unlocked.
