Is AUTHOR wrong in the post ? POST : Im just gonna come straight to the point, i planned my suicide allready and I probably have severe depression. (its "probably" because i only made online Tests yet, wich are not accurate a lot of times, because I dont want my family to notice)

I read a lot on the Internet that if I want These thought to go away I will have to talk with someone about it but I have no friends and as I told you before I dont want my family to notice so talking to my family or going to a therapyst is out of question.

The only Person I could talk about this with is someone from my class because She is the only one I talk with. 
She always tries to cheer me up but I dont want to tell her because if I would I would make her life a lot harder because I would push my self on her and make me her burden and its like "im her Problem now and she has to take care of me" but She doesnt really know me (we only talked like 3 times because we've only been in class toghether for about 2 weeks) so why should I be allowed to make me her problem, its my problem and Not hers, but i have nobody else to talk about this and im really fucking depressed, I dont want to do anything accept sleep, i dont have an Appetite anymore, I planned my suicide, I have no energy, Im just a chore to be around, im tired all the time and all these things, but i dont want to Ruin someones live because of that, or should I just stay silent and kill myself and everybodys live would be so much easier. 
What am I supposted to do, please help.
