I’m sorry I am such a failure

I really don’t know who to turn to for comfort. My mom has Alzheimer’s and I don’t think she will understand, plus I wouldn’t want to burden her if she did. I’m not close to my siblings, and I wouldn’t want them to know what a failure I am. I had accepted a job offer and was set to start this coming Monday ( I recently got my RN license) , so I quit my current job. I had been there for the past ten years, and I loved being a dispatcher. However, Friday morning this new job tells me they rescinded their job offer. The only explanation was that it came from corporate that one of my references failed me. My current job had already processed my exit paperwork and could not keep me. I don’t have a job. I have always worked for what I need. I am the primary income earner in my home for my mom and son. I am scared. I am such a failure. I am used to being “super mom” and right now I feel so low. I really don’t see any value in myself. If my job didn’t keep me and this new one dropped me so quick, then what’s the point. Yes there is retirement, but if I withdraw it, I lose a big chunk of it. And the system I applied for oversees most of the hospitals in my area and I cannot reapply for 2 years. I have put applications out anywhere I can. I feel so worthless. My son has back to school expenses, there are bills, mortgage, groceries... Idk I’m used to taking care of all of it. I’m sorry if I sound whiny or childish but I feel like I’m stuck in a limbo. I really wanted to start my RN career. I don’t know anyone or have family in the medical or nursing field, so I felt proud that I was hired somewhere without that help. Now my only options are to work 90 minutes away, or 2 hours away. My concern is cost and transportation because I do have to take my son to school when it starts up again. He also does sports so there’s that to worry about. I’m sorry if I’m rambling, I am worried about everything.
