Wishing you the best of luck. I truly am sorry that you have found yourself on such tough times. I understand you are working but perhaps a second job even for a few hours a week would bring some extra cash in.
There are times in many people lives when we have to work two jobs until things change. My sister had to work for four years 7 days a week to support herself and her kids. She worked on one horse farm during the week and mucked out stalls on the weekend at another for extra money.
She used to be so tired she could hardly move, but as she liked to say she was thin and in shape. That is called looking on the bright side.
There were times when she was almost in tears from the hard work but she made it and raised her three kids without a man and now is in a better place. You will be as well. Don't give up, just put your head up, work hard and it will be ok, maybe not today or next week but you WILL get there. Again best of luck.
