what to do

Hi there, I'm fifteen yr old male and I don't see myself making it to my twenties. I got diagnosed with depression about a yr ago in freshmen yr. I confessed during a welfare check that I was gonna overdose on pills that my mom stored in a box somewhere in the house. They decided to put me in a mental hospital where I stayed for about two weeks. Ever since then I've been put on Zoloft and I have been a consistent worrisome to my family. As of right now I've developed a sort of an addiction to vaping and planning to buy one of own soon, instead of leeching off of my friends for it. I know I won't have to deal with anything anymore soon probably (hopefully).
