Feeling totally burnt out at 59?

I reached a similar place, in my hitherto fulfilling career as a social worker, in my late 50s. My manager triggered my dissociation by telling me creativity is a luxury in Social Work. My career to that point has been fueled by creativity in meeting need with innovation where necessary. I checked my pension fund took early retirement at 62, moved with DH hundreds of miles to help with first grandbaby. I did business training intending to use my interest in felt making to make a living but got side tracked into a venture which had to be shelved at the start of the pandemic. By then we had found we could easily live on our - small pensions - . My business partner had undertaken further training in non profit business and now runs a very successful mental health project with significant funding from the NHS. I have never regretted walking away from the career I loved and feel further vindicated at every family gathering where we now have 3 grandchildren...

Could you be creative.....e.g rent out rooms/host students/ do freelance?

What a disgrace that we have to wait to 66.
