Am still struggling mentally, somethings have improved the panic attacks, although I still feel so overwhelmed at doing lots of things.

I am still off work due to ring my manager today. Don't feel ready to go back yet.
Have fit note till end of this month.
Should I just go back?? What if I am like this in another 2 weeks. I have to go back to work at some point.
I know we are still v short staffed so thats adding to my anxiety as I don't feel I can cope with additional pressure at the min.
The situation at work won't change for a while and has been ongoing for a long time now.
I am so fed up and dont know what to do for the best.
I have a review with the Gp on Monday to discuss the increased dosage of Fluoxetine I started 2 weeks ago.
