well theres a lot of different options as far as treatment
there's outpatient, inpatient and a little thing inbetween most people call partial.
Outpatient is all different it can be seeing your therapist 1-5 times a week. Or it can more intensive. Where you have group therapies with it. It just depends.
Partial is next in line. It's partial hospitalization. Its kinda like inpatient. But you get to go home to your bed at night. Its like 6-8 hours a day... with group therapies. ad fun therapies like art therapy and yoga. movement therapt, music etc.
heres the description of the one i was in.
"The Day Partial Program provides a more intensive structure for group therapy meeting five days a week (Monday - Thursday 12:00 p.m. - 7:00 p.m. and Friday 11:00 a.m. - 2:00 p.m.) These groups include two meals a day, as well as psycho-educational and psychodynamically oriented group therapy. A personalized treatment plan, including individual, family and group therapy, is designed to address each client's specific needs and goals. Psychiatric evaluation and medication are available, as well as regular medical evaluation to assess progress"
and then inpatient is just like above just more intensive and you have to stay there.
As far as "how bad you have to be". I dont really know... nobodyd does... it really depends on the person. If its taken over your life... then its time to seek an opinion. One thing i will say is weight doesnt matter. As many times as ive been inpatient ive been in there with girls of all sizes... trust me. Ive been inpatient at normal sizes and even overweight sizes... as well as underweight... weight doesnt matter....
