Looking for a fresh new start

I have been living by myself for 6 years, with no family to call my own. I've been recently let go of my company and had been having difficulty finding a job. Fortunately, I received a job offer and am currently undergoing online training. However, my job requires me to set up a work from home setup with a certain PC/laptop specification. I am 2 months behind paying my rent and electricity and don't have money to follow up on pre-work requirements, and am really running out of options how to feed myself. I have a heart condition but I'm doing my best to manage it by thinking positive, since my blood pressure can get high and my chronic anxiety contributes to it. I tried to reach out to relatives and friends but was only met with either silence or non-acknowledgement. I don't know where else to turn to, and I'm afraid of losing everything. Everything's looking positive as far as my training goes, I just have a limited time frame securing my place to stay and work setup as well as my pre-work requirements. Please help me secure my shelter and work, I don't have anybody else in life
