I Don’t Know What To Do

I’ve recently moved countries (From America to South Korea) and I know I’m depressed. Theres no doubt about it. I’ve been depressed since i was in 6th grade, so for about 3 years now. And I’ve made up my mind that I’m going to kill myself very soon. People tell me everything’s going to get better but for the past 3 years, everything has been getting worse and worse. I found out about the medicine ******** I believe, but I’m still working on how to get it. I’m 16 and I’ll obviously need a parents permission. I just want this process sped up. But i was wondering if it was legal in all countries? I just want it all the end. It’s so hard and scary growing up and I don’t want to stay here. I’ve heard people say people that commit suicide are ‘selfish’ but I completely disagree. We didn’t have a choice to be in this world. We were in a way forced to be here. But I do understand where that statement comes from. But, anyways, if anyone could tell me if any ******** is available in Korea, it’d be so appreciated.
