Dear Wocko,
Like many reading your recent post, I'm sorry to hear that you have recently lost your job and the addition stress placed upon you has also led you into depression as well.
As you will know, both stress and depression are two factors that can make normal B/G levels go erratic if not go sky high.
In my career, when I was able to work before I lost most of my sight, I was made redundent twice. I found that it was oh. so easy to slip into depression and mighty hard to get out of it. If you can, and I know it will be difficult initially, fill you time and mind with activieties that you always intended to do but never had the time. Take up a fresh hobby, study something of intrest to you or simply do anything constructive that fills your time and don't alow yourself to slip back into depression.
In my case I spent several years studying all that I could find about my own diabetes not just here in the UK but from anywhere in the world that I could source information from. I'm still working at it even now, and putting most my findings into a book that I'm currently in the process of writing that details my own diabetic experiences in dealing with the NHS as the patient or customer as they might look upon it.
Looking for suitable work and dealing with the 'faceless wonders' at the job centre' was certainly stressfull, but focus your mind on your intrests or studies, and you'll get yourself through this. I did.
With my best regards - Lazybones
