(Sorry if I posted this in the wrong place, I've just joined this forum)

My brain has developed this horrible habit of constantly checking on if I feel anxious ect
I will feel completely fine no anxiety then my brain goes "wait..im feeling normal! no anxiety!" and then of course I remember and start to feel anxious again
The thought is just so automatic and my body reacts with anxiety automatically. It's like my brain doesn't want me to feel normal!!
Has anyone got any tips for combating thoughts like these?
