Personally Nathan, I think working would be good for you and your mental health.
If you sell up, and become a full time carer, you’ll lose a lot of self worth, freedom and ‘me’ time.
I think you’d regret it. Then again, I could be completely wrong.
I think you should make the decision when lockdown is over. You might feel differently then. It’s generally a bad idea to make big decisions during stressful short term situations.
Try to see it through to the end of lockdown. Even it means doing just a £100 a day.
