I have no good advice for OP. I'm in a similar position having been umeployed since Q2 of 2020 after suffering from burnout. I didn't do anything to develop technical skills or networking-wise during long bouts of depression. I'm only now recovered enough to think about entering the workforce again.

My current plan is to get a simple job in the food industry or public health services and then use what remains of the day to attain book knowledge in programming, project management and negotiation. Starting to build a portfolio from now on and trying to make contacts within the industry, hoping that perhaps in a year from now, I will find a 'real' job in the tech sector. Not an easy feat at 41.
