Yeah, it's a pretty dark website, but that's why I really like it. You can just say whatever pretty much. For the most part anyway.
Question for everyone, at what age is the "Turning point" (roughly speaking) where you could say "Alright this person is most likely fucked/wont change"
In the ground.
I'm not kidding.
I'm more than double your age and have had multiple massive changes in life, lifestyle, points of view, and senses of self since I was 22, many good, some bad. Life is not over at 25 or 30 or 50 or 90.
Large-scale goal talk may be beyond you at this moment. If things are really as dark as you say, you need - as I've said before - the basics. If you have a roof over your head and food to eat, then you need to set about finding those additional resources than can help you get the fog lifted so you can start to put some shape to your life.
Side note: arrogance and egoism can exist even when you're doubting yourself or suffering, and those things are often what's between a person and their contentment and success.
Reality: just doing the damn work and not making it a "principled" (ego) thing works far better, causes less anxiety and fear, and though hard work is hard work, is freeing.
You're not expected to have everything sorted at 22. But if you're not just being self-indulgent and really are as bad off as you sound/say (or even if not that bad), you have got to start thinking about how to bootstrap your life.
And you should get honest with yourself. If one of the reasons you're clinging to this state of mind/self-perception is because of a personal attitude, emotions, or unhappy-but-familiar ideas about yourself, then the corrective action plan for you starts with dismantling that. Which is what people mean when they say, "get over it." No, it's not necessarily easy, but until your head is unstuck from where it's lodged, your world is limited. And so - whether that is with professionals or something you dedicate yourself to taking on yourself, you need to start chipping at what you know right now to be part of the root cause. (And what you know right now is only a portion of the actual, but that's what work reveals, if you do it.)
Not sure why, in this time, you've gone 11 years with zero medical or mental health resources, but if that's down to a bad family situation of some sort, you're now old enough to start thinking about what you can change and putting all your effort into it.
Stop grasping for reasons and excuses to fail and stay stuck.
Your parent/s is/are not insured? And you do not work/have no option for employer-based insurance? What is the insurance marketplace like in your state - have you talked to them?
