@Bow I like that, to live despite the struggle. It's similar to something I said in another thread - bravery is not absence of fear but to act in spite of it.
Also, for the record what you are saying about feeling as though it is easier to simply continue as you are - I know that feeling, and I also hear it and see it so often. We are creatures of habit, and we can become comfortable in our melancholy, settled in sadness.
A concept that might be relevant is something Irvin Yalom (my fav existential author/psychotherapist) described as 'groundlessness': if we have complete freedom (i.e. we are solely responsible for our own lives and how we choose to be in them), who we choose to be in this world, it can create a deep sense of anxiety; a paralysing type of dread at the sheer magnitude of possibilities. Sometimes, it can be legitimately terrifying to think of what 'getting better' might look like, because... who will you be then?
I think that's why I like the Stephen Fry quote, as it gives me the freedom to say "I am not one thing, I am whoever I am in this moment, and I can choose to be whatever and whoever I wish, because I cannot be defined by only one thing." Or that is my interpretation anyway. Your ED is part of you right now, and it might be the loudest, but it doesn't have to define you. Listening to those other parts of you takes practice, perhaps because the ED part is the part that is hurt, and so it screams for attention. Giving space to the other parts of you is hard, for sure. I hope it's something your therapist can help you to do; I know for me it was easier to listen to those deep, core-value parts of myself when I had the help of someone who believed in me.
Wow we are touching on some super existential stuff here! I hope you're finding it helpful, sounds like you're processing quite a lot right now. You're doing amazingly by the way, even just the fact that you're asking yourself these kinds of questions is such an important part of the process of growth. I think you can be proud of that.
