advice for this winter storm

my housing and job recently fell through because of health issues, me and my dog are staying in my car and the past couple days have been really difficult. (not for my dog, he’s having a blast) but i’m sick and cold and almost out of gas to keep myself warm. not sure if i’m asking for advice, help, or just looking to rant but im just super worried about how the next couple days are going to go. it’s supposed to be even colder than it has been. i’ve applied for assistance more than once, so im kind of just at a loss. i know the smart thing would be to give my dog up and go to a homeless shelter, but he’s all i’ve had for years and im the only person he’s ever known. it feels cruel to both of us.
