You can't always change your circumstances, but you can usually help them. I've been dealing with mental health challenges my entire life, which means I've come up with a few coping mechanisms that really help me. I've seen these things help other people as well, and I'm hoping that they can come to an even greater use if I post them online.
When you're anxious, sometimes it can help to have your hands moving. This is where fiddles come in. Fiddles are just objects that keep your hands busy, and they come in all shapes and sizes. Tangles are these things that you can twist. They come in all different sizes and textures, so there's one for everyone. Usually they are fairly small, about the size of your hand when uncurled and in a rough circle, but giant ones are also available. I'd recommend following the link I've provided and looking at the Tangles, or trying to find a video on them.
Other fiddles could be something simple, like a stress ball. You could buy pipe cleaners and pull the fuzz from them. Of course, none of those things are very convenient when you're in public. That's where jewelry fiddles are great. They look just like regular rings, bracelets, or necklaces, but you can spin or twist them when you're anxious.
I realize that all of this is hard to visualize. What does a fiddle ring look like?! So, I've created a Pinterest board where you can see example of some of the different fiddles I've mentioned today. If you have any other questions, though, please feel free to leave a comment here or on Pinterest. If you find anything in this post helpful, stay tuned for future posts, because I plan on making more with similar themes. No one struggling with mental illness should have to feel alone, or struggle more than they have to.
