That weird guy who confessed to me

This was a very random and unconfortable experience for me so I though why not share it here? Probably no one will read it but it feels nice to open up. Anyways, I have known this person for several years now as we were classmates from middle school to highschool, we have kinda simmilar interests(?) (Basically anime so not really) but I never really liked him as a person idk why he just had a vibe that made me uncomfortable and anxious. The point is that several times he made up lies about himself that were honestly pretty stupid and made me cringe hard, first one was that he was a popular youtuber ane he gameplayed with several other popular ones, another one was about him having a bf from a neighboring school that's known for having really cute guys and telling me about their "private" interactions (he said this after I mentioned this school to him). Even though I always got irritated around him, throughout the years many times we tried to be friends but I just never felt comfortable and pulled out, I stopped talking to him completely after he made fun of my last name in front of the entire class and made me cry.

During my first year of highschool he was getting along with most if not all my really close friends (not to the point of best friends but he hung around sometimes) and I was okay with it, enduring having him around in spite of my anxiety, telling myself that I was just being mean and I should do that for my friends. The thing is one day he asked if he could talk to me in private and I said yes....he told me as if it was a huge secret that his name was not his real name and instead was one that sounded very western (mind you we're from a country that doesn't have those), that he had been adopted after his Italian family was endangered because of the mafia that killed his mother and some of his siblings, I honestly didn't believe a word he said, then he told me that he had an incurable disease and he was probably going to die by next year (he never mentioned what disease and I didn't ask cause I honestly knew he would come up with an excuse to not tell me)(btw he's still very much alive after several years) he said his Italian brother was the only one who could get him the medicine and that he had private classes about his family's history.....this all sounded so fake but he was my friends' friend so there came the crocodile tears of mine and I even hugged him.

After that day I tried to avoid him as much as possible, call me a bitch but I told all of this to one of my friends even when he told me not to and apparently he had told the same to her and we agreed to distance ourselves from him, the problem was, he would follow us everywhere even when we ignored him and I looked at him with clear distaste, he would ramble on and we would just stay quiet pretending to be tying up our shoes for like 20 minutes. I'm not a confrontational person so i just sucked it up; I specifically remember this one time he asked to talk to me in private again and I told him later and he kept on asking, I was so scared for some reason I latched onto one of my friends and kept rambling and making eye contact with that friend so he didn't have a chance to talk to me, he gave up after that but every once in a while he appeared while I was going home or going to my classroom saying he was feeling so sick and shaking and halluccinating with his dead mother I told him to go to the nurse and left. After a while I felt he was backing off a bit but during a common friend's birthday I was so happy about being with all of my friends that I was nice to him again and stupidly thought he wouldn't act like before.

One day after a school trip I was running late to go to my grandpa's b-day so I was rushing and he stopped me and gave me some folded papers I just took them and left running. I didn't remember this until about midnight with b-day party still going, when i checked the papers (there were like 7 pages filled on both sides) they talked about him being in love with me and how beautiful my name was (continuously repeating it), that I was such a woman and he recalled several events where he wanted to kiss me calling out little details of my appearance I remember all those events and being uncomfortable, followed by lyrics he himself wrote about me, among other things. My anxiety was peaking and I immediately texted my friend in a panic and we agreed we would avoid him at all cost. I was so scared and angry because he did this knowing that on monday we would both be at a school event and I wouldn't be able to avoid him. After that, I showed all of my closest friends the letters and thankfully they sided with me and understood how creeped out I was, after that I burned those papers in New Year's Eve. Everytime I saw him approaching I would literally stand up and run, he left me alone after that but he told some of my friends and not so close friends that I broke his heart and making me out to be a bitch and him a pitiful person, I know this because the ones he said that to came to tell me. I honestly sometimes question myself if I overreacted to the whole situation and if I'm a bad person but those months of living in constant anxiety and being uncomfortable around my own friends weren't something I would ever be willing to put up with again. I still have some pictures of those letters just for evidence and reminding myself I wasn't overreacting, mind you, I speak spanish. Maybe I'm being paranoid but I really hope he never finds this post
