Damn - some right miserable souls in here

Don't go too hard on sleeping dragon, he's obviously practicing the Tough Love which is not unusual, although these days it's kinda out-of-style (for better or for worse). I can see that his heart is in the right place and there are some bits of good advice in what he says, so don't write off.
To be honest, when some people do get pretty far gone/lost in their own funky heads, they do kinda need a shocking "wake the hell up!" call. Unless you are truly clinically depressed and so far out of it, it might not be too difficult to realize (with a little work, perspective) that one's problems are simply borne out of confusion, being misguided, shitty circumstances... But not necessarily "wellllll you're fucked, might as well call it a life.." if the latter were truly so, no one would really complain or discuss it ever (or try to help) because no one would care if it really was their problem, and no one would be able to relate to it either anyway.
That's just the thing, so many of us can relate, so many of us have been there, still are there, maybe some of us never quite shake free of what haunts us, but as we mature it really does become part of the deeper definition of our character. The true challenge then becomes not merely how to "get rid" of this dark part of yourself, but how to live with it, hell how to embrace it and become strong from it.
Our fucked-up-ness, our flawed character is what makes us interesting, unique, special. It's what makes art twisted, it's what makes horror movies cynical and disturbing, it's what makes really dark humor so funny and primitively engaging. If everyone was doped-up-peaceful happy to their core, the world would be bland, uninteresting, grey... Pointless.
This might sound sort of sad, defeatist, but the message here is that if you have some deep issues, it's up to you to make some relative peace with it (on whatever terms you can, and however long it may take) because in plumbing through whatever your problem is very possibly the route to your salvation. It will never just present itself, you do need to go throw yourself out into the world a bit to start exploring whatever it is you are looking for- it might take a long time and multiple tries (and even painful and costly failures, with money, women, jobs, etc) but for each experience you plod through, you will learn "how to get on" in this world much easier and happier than the time before. You'll cross paths with all sorts of different characters, in some ways different versions of yourself who are traveling at different points along that very same path, each feeling just as lost, confused, and frustrated as you are, were, will be... All looking for the same thing, to make that undefinable connection, be it with one another or just simply feeling a completion in themselves.
Getting started, pulling up out of the muck and building forward momentum is really the hardest part. Especially as you are getting older, your pathways are cementing, and you might miss out on some valuable opportunities and feel like you've "missed the boat" for that reason. But hey, society is not quite so figured out that "we dont need any more homers in the no homers club," theres always a constant rewriting of the rules. If you've missed out some important milestones in your life, there's absolutely way more things that you - that anybody - can be exposed to, and to grow from, it just starts from taking some steps, expending some effort, getting out if your comfort zone (or your self enforced prison)
Get off the Internet. Stop fucking around with your smartphone. Stop playing so many video games. Stop getting high every day. Go to the coffee shop and read a magazine. Make yourself go to the bar, get some liquid courage in you and awkwardly buy a drink for the lonely pussy-looking girl at the end of the bar. (do this 4 or 5 times and it starts to get extremely easy, who cares if the first few times you get scowled at). Shoot pool with sine strangers. Go look at fucked up art from 50 years ago or 500 years ago or 5000 years ago. Book a trip to travel to a strange country and take a tour where you'll randomly be forced to spend about a week with about 10 other people from your own culture, it will force you to bond with people you'd never orherwise associate with and learn how to get along just as you are enjoying this fascinating experience together

Go see a shitty punk band for $5 on Wednesday night, go see some dark nerds do stand up, check out some poetry reading. Go to the gym, go for a hike, hurt yourself trying to skateboard, read bukowski.
Do something, stop sitting on your ass and getting older and fatter. I dare you
