I used to fell like that. Like there is nothing u can do. heck I sometimes still do. let me tell u something this might sound like a cliche story but hear me out. I was in 11th grade about mid semester. It wasn't a particularly special day. I was just hanging out with a couple of my friends chilling. For the past 3yr or so I've been feeling totally and completely useless. Average at school, bad at sports even worse with ppl God knows why those two stuck by me for as long as they did.I had nothing I was completely useless. I've been trying so hard not to think about it if I didn't I will probably be in amanuel hospital by now. But there are moments I would just slip into random thoughts at those moments I felt truly useless. Anyways I had one of my slip ups that day and I was feeling pethetic. My friends were of course trying to cheer me up. Then I noticed a pattern most people dont. So I tried manipulating it manipulate ppl. I was good at it...scary good they were like puppets. So for the rest of the day I manipulated ppl and scary part was I liked it. I'm not proud of what I did but there u have it in the end of the day I told them naturally they hated me. So I decided to stop using that particular skill.now a days Im happy knowing that I could do something if push comes to shove as the saying goes. The point of this story is to tell u that everyone has a reason to exist and it's our choice whether or not we follow it. I know lame😂. But that's what I truly believe.
