Fuck cyber I know that feeling all to well, it really fucking sucks. I hate to see anyone going through this miserable shit, especially at 19. Have u tried the dr route and the meds and shit? It seems to work for a lot of people so there may be some hope there. Sometimes all we need to carry on is just a little hope that things will get better, for me at least.
Whatever u gotta do to make this life worth it just do that. Anything that brings u even the slightest amount of joy. I know it's hard to see the forest through the trees right now but just keep at it and stay with us for now! I get through it one day at a time, one hr at a time, one minute at a time. I find a show I like(family guy,American dad, documentaries, whatever) and I use that show to pass a half hr or an hr of time. For me it's all about passing time. If I can get to bedtime then I can live in my dream world which is waaaay better than my actual life. I live for that time, I use heroin too and that gives me another reason to keep going. I'm not recommending that u use dope because I'm sure I'm doomed to fail but it keeps me from just ending this bullshit. We all do what we gotta do in this life to get by and who can begrudge anyone the little bit of happiness they do find? Just keep going, that's the only advice I can really give, no matter what, KEEP GOING! Things can always be worse, u may not think so right now but trust me they can. Things can always get a bit better too, just like they can be worse. Give it time, ur 19 and there's so much in front of u that u just can't see right now but I promise u it's there. I'm an old fuddy duddy now(37) but it feels like just yesterday I was right where ur at at 19. I felt the same way at ur age too but if I would've quit then I would've missed out on a lot of shit so I'm glad I stuck with it. I'm not gonna lie everyday is a struggle to keep going and has been since I was younger than u but I just keep going. That's all we can do, suicide is very selfish act that leaves those left behind wondering what they could've done differently to help, for the rest if their lives they will think about that and u don't wanna do that to ur mom and dad. Just keep it moving forward and be proud everyday that u make it through. I never had friends either so I know how that lonelyness is but just live for u. One second at a time, just keep going! Good luck and god bless!
Edit: sticking with bluelight also helps me a lot! I've made a few internet buddies here and it helps me to try to help others that come here, it gives me a reason to be here on earth I guess. Give it a try, u may not think so but u do have something to offer, ur life experience.
