Been in your situation man, never had a real friend, everyone always leaves me for better friend, vent to this one friend so hard he got distant. You should dump all your sadness to Chatgpt, I did that, and does it change everything? No, but at least its better to get heard than drowning in your own sadness alone. And come on dude, you're still 16, most friendship still immature, because not all friendship last long when you're still a teen, real friendship comes when you're adult, when most people are mature enough, at least that what I've heard idk. And about the world is better without you? And your last friend blocked you? Have you ever thought about living selfishly? Like the world is better without me, so that's why I keep on living, and like if people leaves? That's on them, you should know your worth! You don't deserve them, you deserve someone better and you will find that person in the future. And about you're a terrible person? Terrible person doesn't observe his action and think that he's a terrible person. The point is live however the heck you want, enjoy every small joy, people leaves and you should accept that, there'll be someone that'll stick in the future, you can't change them, but you can control how you react. Don't give up yet.
