SW 22 stone 7 CW 8 stone 2! be aware of how a diet can quickly change into an eating disorder!

Im a 22 year old female, I started at 22 stone 7, 18 months later I am 8 stone 2. I am 5ft6 and my bmi says i should be between 8 stone 3 and 11 stone 1. I have now been diagnosed with anorexia even though I am hardly underweight due to how much weight I have lost and how little i eat. I have not had a period in 8 months, i have low protein levels and my kidney function is not very well! I also have low blood sugar and low blood pressure. I have my first aappointment with an eating specialist on Friday and I'm so scared about going but also really looking forward to getting the help I need. It has damaged my confidence, relationship with friends and family, social life. This is just my journey and to make people aware of how quickly dieting can get hold of you. If someone would of told me 18 months ago when I was 22 stone 7 that in a year and a half you will be anorexic I would of laughed in their faces! If anyone has been through anything like this or even just want tosupport me please feel free to add me!
