Needing some advice

I'm in a similar boat, my job is not stimulating me. I went on leave 5 weeks ago (during that time I did mammogram and got call back and have extended my leave) I was starting to look for other work as I felt sitting in an office with nothing to do and not interacting with other people was having a huge impact on my mental health - it was wasting my life. The last few weeks have reinforced this. The people I work for are really lovely so I hope I can come to some arrangement with them. I am very blessed as my partner can support me financially. I think the suggestions everyone has given you are very valid. If you are successful with your interview, your potential new employer may turn out to be very supportive. Good Luck at the interview!
