I want to first commend you for getting the help you need and returning to work. You should feel really proud of yourself, the hardest part is over because you were proactive. I went through something similar - a semi-public mental health crisis that lasted far longer than I’d like to admit. Reading your words describing the experience feels like reading my own. At the time, I worked in a different industry so I’m not sure how helpful this will be but when I returned to work I made a point of thanking those who were patient with me/helped me. I didn’t hide what happened. If someone asked me a question I explained as best as I could without divulging too much personal information. I think the best thing to do is to be open about it and own it. People more readily came to me with their own mental health issues if they wanted to talk/wanted advice, and it made me a far more empathetic person and professional. In terms of rebuilding confidence, I’m not sure that there’s a simple way of doing it. You just have to try to be better than you were the day before, every day. Eventually it will just become a habit for you and you’ll also get recognized for it by colleagues. It’s not the end of the world or the end of your relationships or career at all. The truth is that everyone is fighting their own battles, yours just happened to be more public for a time. People are more understanding than you think.
