Ugh! That is a tough thing to be going through.
It happened to me with a job I loved that I had been at for 10 years - I was devasted!
It did have bright side though - because of this I had to change my way of thinking and doing things and eventually ended up in a field I really love with way better pay so I think sometimes things do happen for a reason.
I am sure things will get better for you!
Meanwhile hang in there with the weightloss, get out with your friends even if it means trying to do things that are low cost or no cost - you need a support system at times like these.
Good luck to both you and Auntie G in your job searches!
