How do I prevent myself from commiting suicide, even when conditions make me do so?

i am 17yrs and 2yrs back I came to know I was adopted... since then the behaviour of my family members towards me has changed drastically none of them like me anymore... my mother now regrets her decision of adopting me... I have got a terrible skin rash which will never go.. it looks horrible.. over the years I have lots of my friends... and m not comfortable in talking to any of my friends about my problems... I feel like commiting sucide all the time, but there some people I dont want to hurt... especially my boyfriend he wont be able to bare the pain... but these troubles are too much for me to handle... i'm confused... please help me..

My Close friend committed suicide about 9 months back. I was just a very close friend, I see his face every day, his father is 72 years old I am sure he sees his face everyday, his wife is now working hard to take care of his two sons, she too must be missing him much more than me or his father. The point here is there are always people who will care for you no matter what, maybe even after your death... look out for those people you will definitely find them. Look at people who are blind, no legs no hands still care about using this life for purposeful things, dont want to live for yourself - dont !!! but start living for others ... and please dont do something that even your death cannot justify and that is dying like a coward....

Call the non-emergency telephone number for your local police department and ask them for the telephone contact of a local crisis intervention group. They will get you in contact with people who will be glad to help you.

I have been hearing of suicide from people I know. It is not fun for the people who know you. I know a person whos sister tried to OD not too long ago. Her family, friends, and everybody she knew was devestated. They managed to save her but it still put tremendous strain on everybody, including her. Her brother also almost commited suicide a long time ago. For the people who know you, your friends, even your family that adopted you will suffer more than what is making you think about suicide. As Rob said, get some help.

When you commit suicide, the motherfuckers win. Plain and simple. Be a peaceful warrior and fight for your recovery.

When something angers you, close your eyes and think of your happy place.
Example{Think of a dove (the sign of peace) it's flying in clear blue skies with a beautiful sun shining down on you. These are your happy things. Your bad things (which makes you want to commit suicide in the first place) are crows. Your dove is your warrior. Satan's crow is your enemy. Little hummingbirds (or any other pretty bird) are all your loved ones, including your boyfriend. They will fight for you, even if family members don't love you. If they loved you before, why can't they love you now?}
I hope this helps.
Another option is to see a guidance counselor .
