Its exactly the same as the situation I found myself in when my daughter died.
Within 5 weeks I was sent for a medical, where it was decided that as I wasn't rocking or shaking, and had my grandson living with me that I was fit to go back to work.
I could barely get out of bed. My hope was that I may not wake up. My face was covered in huge pimples, and I was barely functioning.
Sent off to the job centre, expected to write a bright and breezy cv, and told I could commute up to 90 mins each way, although they accepted that I may need to look at doing different work. (As if that would make any difference)
