Fighting Homelessness and Alone in this world

I have no other options but to reach out to anyone. I have no family left in this world. My dad died a couple of years ago, and he was it. I have been struggling to stay in this world without him, and then another hit. I got COVID a couple of months ago and was unable to work for almost 2 weeks. I got behind on my notes and lost my car. I have been struggling to make it to work, and yesterday I was let go because of unreliability. I worked at that establishment for 5 years. I feel as though I have no one to lean on in this world. If anything were to happen to me, there's not a soul I could call. Which means no one would even know I was gone, except my little brother, Sam. He was my dad's dog, whom I have now. I probably wouldn't mind being homeless at this point, but I can't fail Sammy. I look at him and I see my dad staring back at me. I don't want to lose him, either. We grieved together, and he is the one thing that keeps me from mourning to death. I'm not asking for a handout, just a hand up.  I don't know where my journey will land, but I start a new job next week. I need some help with rent and groceries during the training phase. Just enough breathing room to actually breathe. I stay in a hotel and only have enough for one more day. Anything will help. Please. thank you in advance.
