First shift at a new job after a breakdown.

I was made redundant as a successful graphic designer, and simultaneously had a breakdown. I have been anxious and depressed for 6-7 months now, and not able to work. I still don't think I should be working as I'm not ready; but I got accepted for a night shelf stacking job at walmart, I applied because I'm desperate for money.

My heart is going nuts. my stomach is in knots. I can't breathe. I feel like crying. I feel like not going. I feel like killing myself.
I really don't want to go, but I don't have a choice. My girlfriend will probably leave me if I don't earn any money. I already owe her £500

I'm leaving to go now. Wish me luck. I need it.

I'm leaving now. wish me luck. I'm so scared.
