Subreddit to find financial help?

I just lost my job and I'm doing cleaning gigs, I have a job interview next monday but my college payment slip is due this week. It's 300 in my currency, which is about 60 dollars. I can show proof and even show the payment slip itself, but I have no one to help me and I'm desperate. Is there a subreddit where people in better conditions help the others? If so, what is it, please?
