Struggling to keep a roof over my head and my dog's paws on the ground

So if you have read my last post and kept up- my gf dumped me because she was caught cheating. She left and I no longer qualify for a 2 bedroom house. My rent went from $81 to $232. I can't pay that on my tiny SSI check with all my other bills. (Thanks ex girlfriend!) None of my few and far in between friends can be a room mate for numerous reason. So now me and my poor 6 month old chiweenie puppy were given 90 days with the landlord and HUD to move. Where you ask with our area being in a housing crisis!? I dunno. Good question. The landlord is only going to make me pay the $81 for rent during the next 3 months. How gracious. I begged the landlord to lower the rent. No dice. But I just can't afford all utilities aka bills on my check with the rent increase . I'm scared I'm going to lose my only happiness now...my dog. I lost my husband to Interstitial lung disease, several friends, and now the place I just got. (Screw the girlfriend part.) I don't know if I can lose much more. I've lost almost all my worldly possessions. My tiny bit of friends I have left said do a GoFundMe...pft. Tried that. It went nowhere. I have a Cash app with a card...but no one has donated. I seriously need help. I need money for a deposit & pet deposit. I can't lose my little Tohma! He was given my late husband's middle name. I just need help. My therapy team helped me start filling out applications all over again. Now I have to repack up all my things. I have been doing nothing but being terrified I'll be homeless, lose my dog, and lose my reborn therapy dolls. I just need help...
