Hi Lexie, welcome to the site - we will all make you feel very welcome, that's for sure!
You've taken the first and hardest steps of admitting you had a problem, talking about it to others and asking for support - well done. I can totally realte to what you have been through and what you are still going through.
I was anorexic for about 2 years during high school, and I wasted away. I'm 5 foot 10 and a 1/2 and when I entered my first year of uni I weighed 50-51kg! My boyfriend at the time (my husband now), was incredibly supportive and helped me through this. I have now put on a huge amount of weight, especially since having my son nearly 3 years ago and I am trying to make a healthy change to my det and exercise. I admit that I still have time where I think "oh, I'll just stop eating for a while and lose some weight and then start eating properly again" but I always talk to my husband when I feel like this and he supports me through those times. I have thought many times about making myself sick to lose weight and again, I talk to my husband. It is scary how it can consume your every thought and deep down when I think really carefully about it, I know that it's not the right way to lose weight, but it is a mental issue that I deal with every week.
I have found the people on this forum so incredibly supportive and I know you will too. I am now into day 3 of the Tony Ferguson diet and I am doing this with the support of Dolly and Hayley D, who also started the diet at the same time.
If ever you feel you need to talk, someone is always here to listen. Congratulations for sharing your story with others and best wishes with your exercise and healthy eating lifestyle.
