bobsgirl, it sounds so painful for you as a mother to see your daughter go through this.
it also sounds as if your daughter is and has been struggling.
I had an eating disorder from my teens right through until my mid twenties. A traumatic, lonely disorder.
I had a difficult upbringing but supportive parents, but no amount of support (from faimily or councelling) could reach me. It took for me to realise that I had a choice to make.
I could either spend the rest of my life in chains, a slave to this disorder and my low self esteem. In which case I'd need to accept that I might shorten my life (being constantly sick, feeling suicidal), ruin further beloved relationships and continue to live in a very private, destructive world. Or I could attemt to accept myself as I was.
This meant accepting i was 'good enough.'
Eating disorders are a habitual way of living. For me breaking the cycle of being sick after eating was key. As was recognising feelings of anxiety and finding other ways of dealing with and rationalising these. You see being sick, I thought gave me control, was a release and a ritual to get me through each and every day.
I have a healthy relationship with food now, but I do regret the years I spent torturing myself. I lost so much and could not accpet the love of some very good people then.
For your daughter it will mean alot that she has been and can be open with you. An eating disorder is hard to admit to, to know you love and accept her will mean everything.
It sounds as if you have tried to support her emotionally and practically e.g with GP.
Unfortunely, it is in her hands as to whether she is ready to move on.
I know that with me I had to reach rock bottom to be able to come back up again. It took discipline and alot of kindness towards myself to relearn a relationship with myself, self esteem and food.
You say that she has a 'nice lifestyle' and 'no obvious problems' and therefore struggle to understand. I can get where you're coming from but self esteem issues are very private, very fundemental and can be crippling (whislt often completly irrational to others), meaning an individual can't enjoy life and it's blessings fully if they don't feel worthy.
I am sorry that she is going through this. I waish I could offer some more practical advice.
I think a good councellor might be worth looking into- but check their credentials and relevant experience. I did have councelling but wasn't able to make good use of it, wasn't able to be open enough at the time.
Your daughter will come through this, it is a painful road. The best you can do is stand close to her and be there to hold her hand and to listen without judgement when she needs you.
