The school counselor is mainly an "academic counselor" so yes, He needs to see an actual psychologist.
He needs to find out if he can take some summer school courses and maybe some online courses.
Also here in Austin, Once you have enough credits to be classified as Junior.. You can attend an alternative Public High School. It is awesome because each student has their own personal guidance counselor with their own academic plans.. and yes, they can graduate with honors and AP courses!
. The student can come and go at their own pace. Some students end up completing their work and finish high school within months and others.. a little longer.
We have known quite a few kids that were just not into all of the "High School social stuff" and also just were ready to move on.. This was an excellent way for them to get the credits they needed and enter college early.. or take a year off and attend College on time, but not have to follow a typical school schedule.
He is obviously depressed and needs to get this balanced out. Depression is a physiological disorder. His brain is not getting the natural chemicals it needs. This can be assisted with medications, exercise and therapy.
Good thing you are all willing to accept this and help him..He is not alone. This happens to most people at some point in their lives.
