Should I just kill my self?

I am having a hard time right now. I think my blood pressure is rising. Dipression is over the top. It is increasing rapidly. I am tired mentally and physically. I really need to learn how to control my emotion and anger that I have right now. What should I do? I cant hold it anymore. I cant bare keeping this pain inside me. I need someone who I really trust! My bestfriend where are you? I keep losing you. I have been searching all over the place? 'sigh' I WANT TO CRY OUTLOUD!
