Have an Answer?
I feel where you are coming from. In my experience life can't really be figured out, at least, I've not been able to and I've been living it for longer :) I have learned that some actions and behaviors produce better outcomes than others, so if I consistently do those things then over time the situation usually improves rather than gets worse.
What are you studying in school and what do you like to do? (Not what do you want to do - what do you LIKE to do?) If you can find a job or career that is in the direction of the things that you like doing, or interest you, that usually works best for most people. I'd be happy to chat some more and see if I can help, or at least offer some support, but it would be good to know a little more about you. You say you want to provide for your family, do you have children, or is it your parents or siblings that you want to help?
If you are comfortable sharing a little more background, I'd like to help.
Let me know if you want to share some more. If not, I wish you all the best anyway :)
