I suffer from Anxiety Disorder, could my multiple panic attacks cause adrenal fatigue?

I suffer from Generalized Anxiety Disorder and am having multiple severe panic attacks a day. I am currently taking Zoloft 100mg which isn’t making a difference. But on top of that I’ve been becoming significantly more fatigued and exhausted during the day doing day to day tasks. I’ve been gaining weight and am struggling to shed the kilos I’ve put on.
My question is could my multiple panic attacks a day be causing adrenal fatigue?
