Hi,
When does she turn 18?
After 18 she is going to make her own decisions.
Try to establish good patterns now, esp birth control.
Talk to her doctor about putting her on birth control -- maybe the IUD. There are new studies about the IUD begin the the most reliable for young people.
(Teenagers are not careful about these things, especially teenagers who are impulsive).

You cannot discipline her. She is sick.
Disciplining her is like insisting that a ten year old with to broken legs go up the stairs on his own to get to bed on time.

The medications she is on cause the weight gain.
With every medication, we have to weigh the benefits with the disadvantages.
Often the disadvantages involve weight gain.
Science is working on the weight gain.
The medications trigger intense cravings for sweets and carbs.
Some medications are less bad than others about those cravings than other medications -- check with her doctor.
