May I pretend you are a dog for the sake of this thread?
If you were a dog, I would advise your owners to try some classical conditioning. I’d ask them, firstly, to find out what your triggers are. Are there any patterns which don’t yet trigger your anxiety? If there are not, could you possibly create some yourself? Finding your trigger and a way to stay below your threshold, away from the trigger, is the first step.
Once they’ve found your trigger, I’d advise your owners to expose you to said trigger but, as mentioned, below threshold. You should not be experiencing any kind of anxiety. If you are feeling anxious at this point, you are actually worsening your fear. You’d be priming your brain to expect bad feelings upon encountering the trigger, which would make it more attentive to anything which may precede the trigger. You don’t want your fear of holes to stop you from looking at google images in general, for example. Don’t be a hero. Start slowly.
You could turn your training into a ritual. Expose yourself to your low-dose-trigger and immediately reward yourself with, for example, a piece of chocolate. Do this a few times a day. A high-value treat will only stay high-value if it is something special…so don’t go eating all your Easter chocolate right before training yourself!
In time, your brain will good feelings when it encounters the low-dose-trigger. Now is the time to make things harder. Look at a slightly more extreme picture, follow up with chocolate. Repeat as needed, until you feel perfectly fine at the thought of moving up another level.
I think you’d make a lovely dog.
