I meant to say yesterday but I didn't. I just wanted to say that even if you've not fainted since it doesn't mean you're fine, it just means simply that you've not fainted, you may still have no energy, a body which can't cope with the energy just needed to survive and have no way to repair itself. It would still be worth getting checked out if you can because the earlier people get checked out the better with an ED so their issues can get sorted. If you say you don't want meds they will try to not put you on them; I've said that with my depression and so they didn't, the doctor I talked to at the time said that was fine except for if I went one day and had clear plans to kill myself and then she would because of her obligation and my health but otherwise she wouldn't and other doctors have also said to me they don't want to put me on meds if I don't want them.
I would say it may be worth getting checked out to see if there is anything physical they can help you with like there may be problems with your blood pressure caused by it or electrolyte imbalances, all things that can be dangerous though they can help you with though the best way would be for you to be on a specially designed eating plan and have your emotional issues looked into, something which they can also sort out for you and though therapy may not have helped in the past sometimes it is just a question of getting the right person and when you get one that you click with it could really help. I'd definately not dismiss it though it is hard going; maybe you could write a letter to your doctor and you could state there that you don't want to go on meds too. They can also treat you as an out patient in a lot of circumstances (some you need to if you have gotten too severe with it) which means not going in to hospital and things so you could also mention that. But, at the end of the day they are all things down to you and it has to be you that decides if you're ready for this or if it is a step too far.
If you've not read it already I would strongly advise you to read the First Aid ED Article I linked to earlier as that gives the medical reasons not to carry out EDs and may also explain some of the things you are feeling. Also, you could contact the supporters on Live Help/
support@recoveryourlife.com and see if they can also help you emotionally.
