I realize none in my family is willing to help me get a job or invest in my future, but i should focus more on my subconscious instead of the 3d realm, "ignore external reality, and only focus on your own inner world"

to quote an anon here:
You don't move the image in the mirror to change it but the reflected source. You need persistence, certainty and coherence but that doesn't come from just playing role games in the 3D. It comes from your imagination, from your inner state, your inner man.
The thing you have to avoid in the 3D is overracting to it. Your life must continue and you can't be happy all time naturally. But you can take things with peace and confidence. If you need to pay a rent and you don't have money, you have to continue living your life but is not the same seeing it and saying "yes, I have to solve that problem in some way" and abording it on a calm way that going full "I don't have money, I will be evicted! Maybe I'm going to eat less! Why does this happens to meee? Bawwww!". You can react but don't dwell there
