Adderall helps with anxiety.
That is not a first line use for Adderall and would not be the first treatment of choice for anxiety.
Depression wipes out the energy to get help or to think straight or to realize it’s time. Going home would be the best at this time. Trying to catch up without friends and support will create more anxiety and lead to deeper depression. It is embarrassing for the young student to admit that they did not make friends. It could be the wrong placement. Mercy is what is needed and it will work out!
I would caution any HS student with serious issues of anxiety and/or depression to think clearly about going too far from family and professional support systems. Also, to consider how a competitive environment will affect him/her.
Very sad, but an 18 y.o. MIT student from colorado allegedly ended his life today. No details about his life were offered. I feel awful for his parents.
