I am very very worried for my friend right now...

When they vented today they said "What am i living for now anyways" and that just set it off for me..
They're making it seem like they want to... Well...
But then they said "if ever i can't hold on be my voice, alright?" And then "Hey if i really do go can you fulfill all the things i wanted to do"
I'm really worried
I can't lose them... Not now...
They're basically the only person i talk to... What do i do.......
If ever i get a super power that makes everyone around me feel happier and better for the price of my own happiness then i'd gladly take it... If i lose them its over...
