It doesn't make sense to me to ask this question on this forum. Wilderness first? Do you think that a general answer is sufficient? No one here knows anything about the specific case (teen) in question. There is no diagnosis. There is no background.
You could walk up to any random stranger on the street and ask this question and get a response that is just as valid as anything you would find on the Internet.
Seek profressional help and guidance, use your own judgement, but do not solicit advice from strangers on the Internet to make such an important decision.
Also, do not depend on one source. Check all angles of this and explore all the alternatives. Do not rush, no matter how urgent you think, or others try to make you think, the situation is.
