Your relapse sounds very much out of control and just you contemplating option 1 scares me. So I'm 100% for option 3, because I don't want you to die either and I for myself know that I can't come out of a true relapse without iP.
Your therapist's advice is odd, I wonder if she sees your relapse as a personal failure that she wants to fix. Just know that this is only and all about you.

Well, I think anxiety is playing a roll in you being consumed by the ED once more. I recall one of your last posts shared you were back at school? And here you mention you don't want to put your life on hold. I think we all believe that really taking stock of our illness and doing long term care is, in essence, putting our life on pause while the rest of the world is out having fun and moving forward. Which, ironically, is what living everyday in active disorder does; shuts down our ability to live our lives. To enjoy small things, to travel without hesitation to indulge in new tastes, sights and culture. It's the barrier that stops you from being alive.

I have removed myself from my schooling on and off for several years when my disorder has become front and centre. In the end it's the healthiest option for me, in that it allows me to focus on what is happening in my life which is causing the stress to ignite the NEED to be in active disorder. It took a long time - I too feared that if I didn't do school quickly and stay with my peers that I would fall behind and be a "failure" - that in the end I have to focus on me. No one else. No barriers or distractions (School and education is my other addiction in it allows me to ignore the real problems facing my life) and really explore who I am.

None of us can tell you what to do, and your therapists can only voice opinions. This is a challenge and in the end it comes down to; do you want to be healthy, happy, or sick and in chronic depression or stress? What has helped me is making lists. I keep an ED notebook of where I want to be in 5 years, and where ED will take me in that time frame if I allow it. I want to be able to go to Italy and eat pasta without feeling guilty. There are numerous wants and desires I can only do once I learn to love myself, through and through.

Be healthy, be strong, and know that you're a unique individual who deserves a moment to breathe, live and explore this world. :)

If you dont put your life on hold (and thats questionable use of words) and get help then there will be no life to hold on to.
Never give up.

i'm all for option 3. i know just how you are feeling. I never did any IP (I've hid my ED from my parents for two years) but its a roller coaster of relapses and weight gain and back again. i'm relapsing too..worse than ever. so maybe this is hippocratic of me to say: you need to do whats safe. everyone with an ED knows the risks, and not everyone with an ED wants to die. Choosing your own fate is the hardest thing in the world! sometimes i wish it were all played out for me and i had no choice but to follow the directions. but that's not the way it works. like i said, my advice is option 3. we both know that its the healthiest option (but not the easiest)

i wish you the best of luck in this decision. Don't loose your will. You aren't alone.
