Homeless Christian need support for school and clothes

I lost my job do to my car breaking down. Once I fixed it it was too late and they would not offer me my job back. Now my car is about to break down again with an 5000$ repair I can't afford. I lost all my friends because they where all drug addicts who only wished me nothing but negative because I chose to become a Christian. My family turned their back on me because they believe in every man for himself. Ive been looking for jobs but with no luck so far. I am currently in a shelter with no money to get to and from places to work in Boston. I am planning on going back to school in the fall until then I want to focus on making sure i don't look homeless. I always had this dream to change the world and do good but it seems like just trying the first steps and getting back on my feet is impossible. I keep getting knocked back 10 steps. I know this attempt is useless but at this point I have no shame and I'm willing to try everything. I just need help and support. If anyone here's this please reach out to me. I will keep you all updated
