Hi Lb,
I truly understand your anxiety regarding work.
I myself was in this position a couple of years back.
For me, the only way forward was to take time off sick.
That way I couldnt "stuff up" at work so therefore I couldnt get into trouble for being late or doing my work poorly.
This gave me enough space to have a back op and get myself ready to return to work fully able to get through the day.
I was respected for this decision. Unfortunately my back problem got worse and I eventually had to resign.
How ever, had my problem been depression at that time, i feel sure that the break from work would have allowed me to work on sessions on this site and my own self esteem without being in the glare of all at work.
You need to put your health and your daughter first.
Remember, we work to enable us to live, not live to go to work.
I wish you good luck in your decision,
be kind to yourself.x
