Being at work with a mental illness is not easy. I have not yet disclosed, but have thought about it, as there are days where it is just too much for me. When I actually just need to be at home and taking time off to look after myself. I am naturally quite hot-headed and tend to shoot my mouth off. And I often regret it. But that's me (Or the bipolar)
Keep your head held high, and as long as you know you're giving it 100%, that's going to have to be good enough for everyone else
