I know exactly how you feel and then some
It sucks I know.
Everything everyone has said is great advice.
Remember that YOU ARE NOT ALONE in this! Heaps of people here know what you are going through, and there are most probably many around you who do as well.
Any person suffering depression who considers suicide is at risk of doing harm to themselves. I have been there. Many many times. I was hospitalised last year for 2 and a half months in a private clinic here in Sydney to be treated for an eating disorder, severe depression, self-mutilation, several suicide attempts...all that jazz...they later diagnosed me with Bipolar Disorder (Manic Depression).
But please please please seek help as soon as possible. I know it's hard, especially because of your financial situation. But there are people everywhere who can help you! Never forget that.
