Post op delemna ( seeking help and advice)!!!

I was feeling depressed,low energy,no motivation then I had a seizure in 2017 .scan found a baseball size meningioma in front part of brain.
After removing all but residual they recommended radiation but I chose to watch and wait.I felt 💯 better for the first 3 years,then I started feeling the way I had previously ( no ambition,no energy,anti-social)during the winter months and seems I would come out of it in the summer.
This last year which is 7years post op all I want to do is sit in my recliner. I’m only 66 years old and this is very depressing,anyone have a similar situation???
