I don't know why I am writing this

Hey there , I am (17) , 6 days back I had my 17th birthday and I am just bored with my life sometimes I thought of I should die because I haven't achieved anything until now that I can make myself proud on . I do new things but I don't feel like having fun or SMTH. I was the happiest , the most energetic ones in my childhood but now things aren't like that It's not that I'm not happy with my life , I love my lifesm, but when I was a child, I had a certain kind of happiness. I mean, us. There was a time like I was so truly me... alive, but now I'm just tired of my life. As the time passed , i gradually realised that was a illusion. Everything Everyone does is for there gain. It's not like i don't have any friends... I have So many good friends but at last we all are alone from the beginning to the end. So i prefer to be alone.. May be I am bored. I am bored of doing those things everyday and in the end I get nothing. I feels so frustrated. And as for getting a love stuff, love doesn't exist in this world anymore; everyone lives for their own personal gain. Your parents also love you because you're their child. If you were not the child of your parents, then even your parents would not like you, Everyone is with each other for their own personal reasons..So Live alone and Die. True happiness can only be achieved only by living alone in this world, by being with yourself only, by living in nature. I don't know why I am writing this may be cuz I want to... Btw thank you for reading... Good Night
