First off, it sounds like a dumb adage, but there is truth in it: ending it is a permanent solution to a temporary problem.

I'm not-so-young, at least for this crowd. It may be a weird way of looking at it, but the way I moved away from thinking about ending it over life pressures is: if my life is already forfeit anyway, I should no longer feel overly pressured to do the thing that was pressuring me so much, since killing myself would definitionally mean I failed anyway. So why not just skip all that and just take the failure and try something else instead? Use that feeling to guide you into moving on. Yes, it's a terrifying unknown, but when you see yourself as a dead man walking anyway, what have you got to lose really? Everyone changes this way over their life, of course, but maybe not everyone does it with this mental framework... but it helped me harness my thought process anyway. I'm not religious in this way, but Buddhists talk about 'welcoming and experiencing all emotions' when being mindful, even 'negative' emotions like panic and depression, instead of fighting them and trying to purge these from your person; I think this is just another way of looking at the same concept. Experience the emotion, embrace it, see where it comes from and why you feel it, and this helps you move on to something else.

So, yeah, I'm still struggling to some extent, but more glad for it than I once was. I'm not fast-responsive, but I am reliably responsive... if you need to bounce thoughts around, feel free to send me a message. If not, just try and hang in there. I can't stress enough how different your life can be in ~10 years, in ways you can never know. I won't promise it'll be better, or worse, but it will almost certainly be a lot different than you imagine.
