I'm sorry to hear that your business has failed and no idea what it was but i'm assuming you were able to work pretty much on your own and that contact with others was limited or that you could to an extent choose who you interacted with

I've always accepted that I needed to work to pay my own way and never had a problem with the concept of work however what i'd say is that for me right from the start it's been made intolerable by the amount of "Fucking Arseholes" i've had to constantly deal with
For many people Covid restrictions were a nightmare as they struggled isolating and wanted / needed to be surrounded by other people to have the day to day interactions, surprisingly a guy I worked with who everyone felt was an abrasive character hated not being in the office

Conversely I loved Lockdown as it meant I could work from home 3/4 days a week and no longer had to interact with these twats face to face on a daily basis

Perhaps get another business going having learned from why the previous one went wrong or you'll simply have to soak it up that you now need to answer to some other prick and put up with all manner of shit.
Sorry i'm probably not helping to give you much hope or cheer at the future but just get your head down and remember nothing is forever and you will get through it

Sounds like you need to get something that is perhaps flexible or hybrid and allows you to work from home some days, alternatively you may need to find something that is fairly solitary, Bramble picking season starts soon
