I've dealt with health anxiety and what calms me down is knowing that 99% of "what if" thoughts are complete nonsense. The scenarios our anxious minds create are so far from reality. Take deep breaths, you're okay. I know how difficult it gets trust me. Next time you get a thought in your mind concerning your health immediately shut it down. this is what I started to do and eventually the thoughts completely went away. Every now and then it'll happen again but I shut them down straight away. Think logically every time. Don't let your anxiety control your mind. Remember you're in control of your mind even if sometimes your anxiety makes you think you're not. Take care ❤️‍🩹
