Hello! Sorry i had a whole message typed out on my phone, then it died on me, so this wont be as long or detailed as it could of been. But i'll try and put in as much as i can remember.
I have basically recovered from EDNOS, however the support i recieved on the NHS was terrible, really rubbish. It was made worse becuse i was 17, which isnt quite a child nor a full adult, so they didnt really know what to do with me. I think even if the support you recieve is amazing a lot of it has to come from you anyway.
Dont be too hard on yourself, this is your first relapse and probably wont be your last, but relapses are a normal part of recovery. I think it becomes easier when you are spending more days eating normally, than starving yourself, bingeing or purging. When this happens your brain begins to function probably again and staying on track becomes much easier.
I only suffered from bulimia for about a year, after being discharged from hospital with annorexia, as i felt i put on weight too quickly because of the IVs and eating plans. I managed to tackle it first from the purging aspect, not allowing myself to throw up. I concentrated on that, no matter how much i binged, and i eventually i realised that starving myself led to binging, which led to further weight gain, so i was able to curb the bingeing aspect as well.
The key is really finding reasons to live and stay well for. I have never been a motivated person, but i wanted to move out, so i got a job, i enjoyed working, socialising, volunteering, pub trips, take aways and weekends visitng friends around the country. All these little things i needed to be well to do, so i concentrated on them rather than on my eating habits or weight. Execrcise classes in the evening are a great thing to do to. Try concentrating on things youve always wanted to do, that dont involve controlling your weight or physical appearance in some way, and these things will helpt to distract you. Try to acknowledge the things in life that bring you happiness.
I have maintained a healthy weigh for quite some time now, with several relapses along the way, that have become less drastic and few and far between. I dont engage with diets or diet culture at all, or else i feel an instant relapse coming on. Ive learnt that im ok with being how i am, i still get just as much joy from life (in fact a lot lot more) than when i was 4stone.
Good luck :)
