I just need to vent about starting my weight loss journey

I went to the doctor for the first time in 2 years and I found out I am 415 pounds at 6’4. I knew I had gained weight since my son was born and other life events happened that led me to eating fast food all the time and generally being a slob. However I was absolutely shocked at that number, as I thought I was 350 at the most, which is still too much obviously. My test results then showed high cholesterol and potential fatty liver if I didn’t lose weight. I started my journey this week by tracking my food and cutting out fast food cold turkey. I stayed well below the calorie goal on MyFitnessPal for a week and I feel that my diet may take this time. I’ve tried several times before to track my food and have failed every time. This time will be different. A year from now I will be healthier and happier in my life. Thank you for reading.
