Sending lots of love to you @FurForksSake
I my experience, sometimes people are drawn to careers in mental health because they've had their own struggles but I can imagine sometimes that can be overwhelming, especially if you are empathetic and dealing with your own stuff.
I truly hope you will feel better in some way when you are back at work. I am in no way belittling it, but it's like that Sunday feeling of anxiety X a thousand for phased return. I often feel anxious about work when I've had a break and usually I feel better when I'm just back in it, despite the challenges. Of course, it would be better all round if we just didn't have to work.
In my fantasy life, I'd be waking up in my cottage by the sea not needing to do anything at all other than read, mess about with my dog (which I also don't have) and dabble back in some art.
I will buy a lottery ticket and send some your way if I win!
