Consider disclosing to at least one trusted person you will be working with, so you have someone to seek support from if needed.
If you work for a supportive organisation and feel comfortable sharing your mental health journey, talk to them about what you need. It can be worthwhile to share with company management, too, confirming that you are prepared for the festival season, and you have a management plan in place.
However, it is important to remember that there is no obligation for you to disclose any personal health or mental health information, this advice is just as a suggestion for your safety management plan.
You might need to be quite firm about your needs and boundaries.
That’s OK – your health is the most important thing.
