It's like anyone who's going through some sort of depression thinks that they're a special snowflake and no one else will ever understand how they feel, and no one else has ever gone through anything that they are going through. You are not special. You don't mean s**t to the world. Just because you're depressed and suicidal doesn't mean the world will stop spinning just for you.
And maybe you should try listening to the people who have been through this s**t before and lived to tell the tale. They know what they're talking about more than you. When you finally get through your bullshit and get on with your life, then you'll be that person. But right now you're just a piece of s**t and you're really annoying looking for attention all the time.
