Hi @myfirstlove and welcome to the online forums! We're glad that you have joined our community 😊
I'm so sorry that you are having to deal with DP/DR, and understand that this would be quite exhausting and distressing for you, especially when out in public. It's very brave of you to open up and start talking about this, can I ask if you currently have any support in place, or have a specific way that you can take care of yourself? Have you talked to anyone about what is going on for you?
If you do want to talk to someone, Kids Help Line are a really great and non-judgmental support service that are available over the phone or by online chat, and if you've not contacted a helpline before, here is a really good overview of what to expect.
