Do you have a comfort item?
I have a comfort blanket which I carry round with me. Sometimes I carry it out in the open if I’m feeling more anxious than normal but most of the time it stays in my bag. Just knowing it’s there makes a huge difference for me. When I’m at home I always leave it on my bed and make sure it’s neatly folded in a certain way.
I’ve also got a comfort bear but she stays on my bed. I got her when I was six and she’s been my comfort bear ever since then really.
