hello, my name is Nourdin i am currently 17 and i am depressed

you may wonder why? so i will explain the whole story

and before i do this don't think i am just joking or am just going thru a typical phase this is a faithful story.

so last summer i had long hair and i didn't think much of it i was always the average looking guy and i didn't get much attention from anyone but when i grew my hair out long i started noticing that people became nicer to me, and girls were starting to look at me but i didn't think much of it. Then it was summer and i went to France to visit my grandma and my grandma signed me up for a Summercamp where it's just you and a bunch of people hang out at the camp and go to different places so i go there and the first thing that happened was a lot of girls were looking at me and i didn't know why i never had any girl look at me let anyone bunch of girls so we all had to sit around the table for a meeting to introduce ourself and everyone did and when i started talking compared to the other guys girls were asking me questions and all type of stuff which made me feel happy and liked. the next day i go there again and 3 girls asked for my snapchat and Instagram which was so weird to me because no girl ever asked me for any socials i was always the one chasing them like a dog chasing treats but they randomly started to chase me which i couldn't fully understand and i gave them it and they started talking to me and now i had like 3 girls texting me at the same time trying to talk to me which never happened. so anyways after the camp i go and play volleyball and then i keep seeing girls stare at me again and i finally understood i am good looking!!! i had girls from the age of 16-40 i would say look at me smiling and stuff it was so crazy to me that even old woman were looking at me people were respecting me more and i had guys trying to be friends with me for absolute no reason so anyways i thought i was just good looking naturally like i thought maybe i just had a glow-up and didnt think much of it until i cut my hair i made my hair short again because it was getting so long to the point it kept going in my mouth and covering my sight so i cut it short again around eyebrow level and then....... everything changed i go back to school and no girls were even looking at me or wanting to talk to me guys didn't really wanna be my friends like it was me trying to be friends with them and i was being treated way different it was like I'm living a complete different life and this has taking a effect on me in a negative way i am now super depressed because i was so liked and out of nowhere i am like invincible to girls  i even try talking to some of them but it never leads to anything because they are not attracted to me now i am slowly growing my hair back to the length it was before but it will take me probably another 6 months and i don't know how i can keep going like this it has changed my life so much i can't focus on school always stressing now thinking if i will ever get a girl that will like me all this stuff is just making my head hurt and i can't focus on anything and i am starting to feel like i am worthless to the world and don't know what to do i have become a lost soul and i am stuck in this mirage of how i used to be good looking and likeable i am just another worthless soul that just ceases to exist and i don't know what to do can someone give me some tips? whoever is reading this i thank you for your time and kindness to feel what i am going thru its just so hard for me right now because it's like i was in a bright happy life and now I'm in a shadow realm full of darkness and hatred.
