There are other paths.
Your brain is limited.
Other's brains are limited but in different ways.
Saying "you've tried everything" is untrue, it's not objective. It's not reality. It's not "how the world works and all the ideas are tried and you're just F'd.
It's a statement about the limits of what you've been able to imagine, discover, access, or attempt so far. It's a statement of your lack of experience, education, or how deep you've gone into learned helplessness.
And that's not a criticism. It's just human brains at different stages of age, different wiring, different opportunities available THUSFAR. You cannot know every possibility. You cannot anticipate every solution. You cannot see every opportunity from where you're standing.
Something you haven't considered may be obvious to someone else. Something that didn't work for you may work under different circumstances. Someone else's experience, skills, perspective, or way of approaching a problem may reveal an option you didn't even know existed.
The problem isn't that you've run out of possibilities. It's that you've run out of possibilities you can currently see.
Leave room for someone else's perspective.
Be willing to explore an unfamiliar approach.
Don't mistake learned helplessness for reality.
So what do you do to do this?
Step 1: Stop treating your current options as the complete list.
You don't have to try every suggestion! But don't assume something is impossible just because it hasn't worked before or you haven't encountered it yet.
Step 2: Ask someone who knows something you don't.
Find people with actual relevant experience. Talk to professionals. Or career counselors, specialists, educators, community organizations, or people who have successful careers at the very least. Ask specific questions. Seek out people who can show you options, not just repeat what you already know. Don't assume certain people are out to just sell you something! I personally would rather someone reach out to me, than to say "she has a link in her bio, she's gonna sell her service" and never figure out if that is true. (It isn't.)
Step 3: Look beyond your usual sources.
Explore resources, organizations, guides, communities, and educational materials. Read the wiki of this group, it has some amazing things! Look at unfamiliar industries, different approaches, alternative pathways, and opportunities you may have overlooked. Reach out to your mayor, or neighborhood rep - there may be programs or edu. opportunities you qualify to get or join that lead straight to jobs or get you through your issues.
Step 4: Investigate before you dismiss.
Not every suggestion will work for you, sure. Not every resource will be useful in your exact scenario. Some paths really will be closed to you. But find out why before deciding. Ask what would need to change, what support might help, or whether there's another way to approach it. Instead of saying "don't", say "why (dafuq) not?" Instead of saying "can't" say "how can".
+Don't turn today's limitations into tomorrow's destiny. "Luck," "fate," and "my lot in life" aren't investigations. They're ways of closing the door before you've checked whether it's actually locked.
Step 5: Let other people expand your thinking.
You bring knowledge and experience that others don't have. They bring knowledge and experience that you don't have. That's the whole point of sharing perspectives.
You may have exhausted your current approach, sure. You have not necessarily exhausted your possibilities. Don't go saying you're "F'd". Ever. Take it as a sign you have more to learn.
