Tough love approach here so please don't take this as preachy, god knows I am struggling terribly and have my own family to deal with....but back to you.

You say you are in T and doing everything asked of you to fight the ED yet you are trying to decide if you should leave your family so you can continue behaviors? Are you really fighting the disease? Do you plan to fight and work just as hard in therapy if you leave your family? Are you looking for a reason to leave your H? Or is just the thought of recovery, and someone loving and caring enough about you to want you to get better so overwhelming that you are clinging to the eating disorder mindset for dear life?
