Similar thoughts come to my mind as well, for me I came to realize it isn't depression but a lot of stress. Killing myself is easier than dealing with it. For you, I cannot say but talking about it can help you better understand it.

?!?!? dont go through with it.... It will only bring heartache to those who love you. And im hoping that by random thoughts you mean you are not thinking about it often. Have you had a recent tramua or death of a loved one? Many times those kinds of experiences can cause deep depression or feelings of hopelessness. Don't give in to the sadness. Its ok to cry and get it all out but you have to keep going on. You only get your one life to live, so treasure it and wait for better days

If you shoot yourself in the head, use a shotgun. It should be better at making sure you don't survive with brain damage. Probably not the type of comment you were expecting, but you can't pretend it isn't helpful.

ive been feeling that way too im just not happy life is bullshit

sometimes when you try stuff you could make your life worse just for trying, ive heard of people shooting themselves in the head and ending up blind, maybe you should get some help instead
