Having just requalified as a Mental Health First Aider, I was reminded again of the value of the stress container model when speaking with people about the stresses they experience, and how to manage them.
MHFA England offers a variety of free resources on their website and a good starting point might be https://mhfaengland.org/mhfa-centre/resources/address-your-stress. They can also connect you with MHFA trainers if you want to get qualified, which I would recommend.
