<human>: Give me the gist of the text in a nutshell

I met someone online almost a year ago, and we quickly became friends. After awhile of talking, we got really close. We have a similar struggle and helped each other through.

As part of this, he made me swear on someone's life that if I ever went back to do the self-destructive thing, I wouldn't talk to that person again. He never swore on anything to stop, and over that past two days, he started doing it again but had no punishment.

I did that thing last night. Because my best friend and I don't keep secrets, I told him. He said he wouldn't talk to me for a week, and after a week, if he determined that he could still talk to me, he still could never trust me again. He also said I betrayed the person I swore on, and, metaphorically, killed him. 

I feel like I've lost everything. I don't know what to do. I've never gone a week without talking to my best friend. I'm a mess. I feel on the edge.
<bot>: I did something I swore I wouldn't do and lost my best friend's trust, and he may never speak to me again.
