11dc's Things

I don't have any social media, and i don't any site that can help me in math. So it would be nice if you all coud recommend me a site or app that could help me in this question.
If anyone is good at math I'll appreciate if you could help me in this question:
f(x)=x/(e^x +1)
Slove :
f(x)=f(m)

So i posted few hours ago this question https://www.mangago.me/thing/about/673702/?filter=date#about_673710
and I just wanted to say I understand why you'all responded like that. and I'm not trying to defend myself for anything. just wanted to be clear that it is my first time feeling those sort of emotions, and yeah I WAS WRONG.
i wanted to confess to a taken guy ( but tbh it was more like I wanted to be back to be friends) but I guess everyone can see that we've been drifting away since long ago, and any relationship I had with him has already ended.
just wanted to say I won't try anything with him. and wanted to thank all of you who answered me, i tried to reply to all of you but there was too many answers.

I'm just really looking for an advice,(I'm not sure tho if this is the best place to ask.)
So I have a crush on someone for 3 years now. 2 years ago, we were classmates and we always talked to each other, mostly about anime and movies. But for the past 2 years i had never exchange any words with him since we aren't classmates anymore, we don't even share eye contact since we rarely see each other. But every day I just realize that I truly love him.(even if sometimes I suspect it's just my attachment issues). The problem here is:
1. He's taken.
2. We both have like this big exam at the end of the year, that will decide our future. I'm afraid if i got in any sort of relationship i will be distracted, and will fail.
3. Even tho we were kinda close?? We stopped talking (mostly my fault because I'm really shy and whenever I wanted to greet him or talk to him outside I find him with his friends anf I get anxious)

So, really what you'all think I should do??

So in few words, I loved my classmate for 3 years and I still love him now. I am now Senior and may not meet him again, I haven't told anyone that I love him, even my friends, because he has a girl he loves, who kind of could be considered a friend of mine. The study will end soon, I can confess to him now, but I live in a f**king third world country In which girls are just object. My parents would kill me if they knew I wanted to date someone, probably I will be mocked because I am in my country a girl who is in love, meaning that she is an easy-to-reach bitch.

anyway, I just feel more comfortable posting such a thing on this site. I really want to take anyone’s advice because I want to face reality. Even if he rejects me, it will be better than continuing in my life with these feelings.
