Please don't give up! While I have not had the loss (so sorry!) I have had to deal with job loss & the frustration of knowing you did it right but can't seem to get/keep a job. There is a job out there for you! There are people there who care! Do you have a spiritual leader you could talk to? If so, not only could they be someone for you to talk to, but they may also be able to help you with therapy!
Please keep us informed on how things are going!
