What happened to my body?

You can be doing the hardest HIIT workouts, intermittent fasting, and barely eating enough to fill you up throughout the day, yet you find yourself gaining weight. Suddenly you have a tire around your middle that wasn’t there before. You will go to your Doctor, and they will tell you to eat less. Count calories. Make sure your input isn’t greater than your output. They will do a blood panel, but it doesn’t throw up any red flags with your hormone levels You feel like you are crawling out of your skin. You have anxiety, you feel uncomfortable all the time, and you are constantly tired. Alcohol makes you feel worse, way worse. You have no sex drive. You are struggling to remember what it feels like to feel “good” or even happy.
