You aren’t a failure.

Not every kind of set up is right for every person. This job might have a wrong set up. Maybe them making people work from home is a bad set up as you don’t get to learn from other people, maybe they aren’t good at providing timely feedback, why aren’t they pointing things out ahead of time? Or maybe your skills could be used in a different field, if you are trained in digital/computer field, then maybe these skills could be used elsewhere: tech support for schools or colleges or hospitals, IT, billing etc Or maybe corporate world isn’t your thing and you need something slower pace. Corporate business world isn’t for everyone
