HELP! Job Market And Seniors

I have been looking for a job since May. Plenty of interviews but no job. I have over 20 years experience in telecommunications, and yes, I have kept up with the technology. I currently am driving a truck for a non- profit but can't even cover my rent. I have maxed all available credit cards and October first will be judgment day. I have run out of options and now I am begging for help. I never thought I would be in this situation. I have two prospects for a good paying job, but my rent and utilities are fastly approaching, with zero on my bank account.
