failed my driving test and i'm so depressed and stressed out i don't want to do anything else and i feel sick

i failed my driving exam this morning and i feel incredibly depressed and stressed out. i didn't expect to feel this way but after failing my emotions have just been extremely overwhelming. it initially started out well but after about a minute the examinator touched the steering wheel because apparently i was gonna hit the curb even though i didn't think so. I didn't even get a chance to drive, she failed me immediately. she was also really rude and had a very cold attitude which immediately put me off. after that my emotions exploded and once i got out of the car i started crying and i was really mad. my dad and my instructor came up to me and i basically just ranted everything to them. after i got home i started crying even more and i couldn't control my self. it's been a few hours and now i'm not crying anymore but i'm just as down. i don't have the motivation to study, or go to the gym, or keep up with my diet. all i wanna do is lay in my bed and cry. my head is hurting a lot too, it feels like it's gonna explode. ¡ don't know what to do to get over it. i'm just so stressed. I'm a senior in high school and i have some really important exams at the end of the year which i have to study a lot for. i really wanted to get this driving stuff over with to focus on that but now i can't. I'm really busy and overwhelmed wit school stuff so i have no idea how i'm gonna do those extra driving lessons. i really wanted this worry to be over with but it's not. i'm even more stressed and i don't feel like doing anything anymore. what sucks even more is that the closest time i'll be able to take the exam again is in february which seems like it's gonna be an eternity. i really wanted my driving license to be able to go wherever i wanted without depending on and stressing out my parents to take me places or spending money on ubers. i just feel like a failure and im more stressed than ever. i'm so down i literally am not able to do anything. i’m literally not motivated to do anything at all anymore. i don’t wanna go to the gym, i don’t wanna study, i don’t wanna hang out with people. i also posted in a few driving specific subs and i got some harsh replies that made me feel even worse. now i feel stupid because i didn’t pass and i feel like a total looser. i’m also even more scared of the exam now as i know what it’s like and the atmosphere is awful.
