What to say for leaving the old job is a tough one ..(eyesclosed said "constructive discharge"). I never heard that..but it is a suggestion. Is the restriction you have based on a disability? I ask that because if it was...you could mention that as a reason for leaving (many companies HIRE people with disabilities to meet some minority quota and get some bonus).

And..if it was a disability restriction that was properly documented by a physician than you have a legal case (using the American Disability Act) against your former employer for possibly not complying with minimum accommodation requests (if they were in writing).

I was in a situation where my Dr. requested accomodation and my employer said they could not meet it...it was all in writing...but my requests were not reasonable for the job I was doing. If your requests were reasonable and not taken seriously..lawsuit.

Example: My job was mostly standup 95%. I was requesting a 80% reduction and suggesting other tasks I COULD do..basically changing the whole job..they said nadda...I lose.

Anyway...EVERYTHING HAPPENS FOR A REASON.
ONE DOOR CLOSES and ANOTHER OPENS....These are not cliche's if you BELIEVE them. Make yourself believe them and everything will work out.

I'm sorry the new job opportunity did not work out..but something else WILL...you are only 39...and you are not a failure...look at this like - YOU ARE BRAVE....you took a stand against employee abuse (not enough staff and too much pressure)....

If you have a genuine disability that you need accommodation for...than get that in writing from a Dr. and hold on to it, in case a situation arises in your next place of employment where you need to present it..and there will be a NEXT employment..

As far as paying rent for January..what is your relationship with your landlord? Work something out...Income tax is coming isn't it? Also, churches in your area (my sister in law) asked a church for help and they paid 1/2 her rent. She was not a patron of the church...she just went there and asked...you just have to live in the same city. A church in my area gave them a gas card. So if you go to a local church..if they can't help you..they may know someone that can.

Go apply for Food Stamps today or tomorrow. Look for soup kitchens in your area (many give away free food to take home)...You will get thru this...
