Please seek help at your university's health clinic; anorexia is a psychological disease and professional help is the only way out. It might seem scary and embarrassing to ask for help initially, but don't you want to feel better about yourself and your life? Are you really living the life you want to be living? It sounds like your ED has taken over your life and now controls you; shouldn't it be the other way around? Wanting to get better is the first step, and if you truly do, and truly want to commit to yourself then take that first step and seek out a health professional. Please do it soon, before your health deteriorates further. Anorexia weakens the heart and other organs and will most definitely cause health problems further down the road is you do not stop now.
