I am in recovery now for anorexia/binge-purge type. I am currently slowly creeping up my weight and I am at 95lbs at 5'5". This is a 10 lb improvement from the end of August. I am happy with the progress but it is still too difficult to eat normally. It is a 24/7 thinking process.
I am also scared about my metabolism going crazy and destroying my recovery. But I cannot fight the natural changes that my body is prone to adapt to. Exercise should be eased in, and yes, weight-training is key as well as light cardio. The cardio exercising should help with your self-esteem and energy levels. It should help give you the rush of having a "good workout" and hopefully keep you going back for more. The weight training is important to toning your body and making sure that your recovery and weight gain shapes your body into something you can be truly proud of.
My body was always naturally lean, almost naturally "skinny". I have always had a boyish body and so it was a surprise to my whole family and the people I love most in my life when they saw a small frame start to wither away and disappear. This, of course, is not what I saw when I looked in the mirror. But yes, the image of a disappearing girl was satisfying.
Now, as I undergo the process of recovery, I look to more than the mirror to try to see what everyone else sees when they look at me.
I have been diagnosed with major depression as well as Rapid Cycling-Bipolar Disease Type 2. I have been put on anti-depressants to help "stabilize" my mood swings. This was something that I never realized in the past. It was scary to be told this by my physician. I thought he was joking at first, only to realize that, yes, it was all true. And it was a problem.
Now the challenge will be for you to convince yourself that people see the outside appearance of us women, judge us, and walk away. But that's it. That's all they can do. What really sticks is a confident appearance and personality made to suit it. If you're beaming with confidence and beauty from the inside and out (yes, it's super corny but really try to embrace what I'm saying!), then people will stop, judge, take back their judgements when they actually try to talk to you. Because they will want to talk to you and get to know who that beautiful woman is.
