I didnt realise it at the time, or as it was happening.
I have ADHD, and can be amazing at work. But over time corporate offices destroyed me. I sought help for depression, and my ADHD. But no one suggested burnout.
I had to have a fully nervous breakdown and six months off work to even work out what was going on.
It's taken a full two years of recovery, and now I guard my mental health like the crown jewels!
But I'll never be the same again. I'll never fully commit to another company, manager, workplace or team again.
I choose to validate myself outside of what makes me money, and choose my friends and acquaintances carefully. I don't assume people I work with are my 'friends', and I certainly am very careful who I trust! (which is never anyone at work!)
