I feel the same way you do its been 2 weeks post for me and i only had it in for 2 weeks but that was long enough for it to do all the crazy things its doing to me now. Lately just like you i have been having bad anxiety get my i mean i have had it pretty much all my life but now its sky rocketed! I am just now starting to feel weird driving but iam trying real hard to not let it get the best of me. Also i have been feeling very sleepy but yet my heart has been beating really hard and fast i feel that and its bothering me. I want to get my hormones tested so bad i bet they are out the roof! I wonder if it has anything to do with hyperthyroid caused by the mirenas fake hormones it puts into your body. I feel like iam speeding 24/7 and rapid weight loss. I hope we start feeling better soon.
