If you are under medical or professional treatment, share this plan with them and ask them if it is OK for you to do this.
If you are under 18, you MUST tell a parent or adult guardian about this training and get their approval or have them help you with it. You MUST NOT use this training without permission from an adult responsible for your welfare.
It's your responsibility to stay safe. You must make your own judgement call on what is a safe situation to speak to people. A public place like a shopping centre or coffee shop is probably OK, but if they suggest going down a dark alley it's probably not safe!
