I believe in being compassionate and understanding and such. I am wondering what you would have us suggest that hasn't been suggested already, and that hasn't been, IDK, dismissed as undoable?
Forgive the cliche' but as they say, "Where there is a will, there is a way." You may not find the way to always be the most ideal, but, so long as it is legal and healthy and right, a way is a way.
Have you thoroughly researched things?
Why wouldn't you be eligible for a Pell Grant?
In school, whether it be a community college or university, you will find that there are student services that can guide you with or direct you to resources for a number of issues you have shared.
You must take the initiative and then keep going.
If you are using a computer at a library, make the best use of your time there in terms of research.
One step at a time, but for God's sake. Take a step.
Prayers & Blessings for/to you.
