I think it’s also important to note that there are no geographical cures in life. Waiting until the end of the term to announce your departure to your parents (who think you’re going to tough it out) and your advisor isn’t a good plan- nor is it fair (or truthful) to the people who are there and want to help you. Right now (instead of self-diagnosing yourself and others) you need to reach out to people who can help you. Ask for help and bring everyone in so you’ll have a solid support system in place while you finish out this term and perhaps the year.
I’ve heard you say that your parents have talked to your advisor but have you? Boarding schools have many safeguards in place for the safety and well-being of their students. I would recommend a visit to the HC immediately and speak to a nurse. Trust me- they’ve heard it all and will help you ( and your parents) during this uncertain time. After you meet with a nurse- she’ll bring everyone together who touches your life on campus ( in a discreet, respectful and confidential way) : Dorm Parents, Advisor, Coaches, Academic Heads and Faculty to help guide and support you. They will also talk with your parents and perhaps make recommendations for on campus/ off campus counseling. They can also recommend that you leave now for treatment.
There are also peer mentors in place ( depending on your level of comfort and the severity of your situation ). In other words… use everything that is available to you now instead of running out the clock. If you are truly suffering from depression and anxiety - switching schools isn’t the cure. Depression and anxiety doesn’t care where you go- it will follow you everywhere. Even to the most beautiful and serene island in the ocean…
You also need to read @ThacherParent 's post again- and again (and again). And, I’ll just add more thing ( pending a Board Certified diagnosis) : You are not the first student who hit a wall at BS ( socially, academically or spiritually) and you won’t be the last. In fact, I can almost guarantee many of your classmates right now are seeking help and receiving it - with a support system in place - and they’re fighting the good fight. Some may have a diagnosis and are taking medication and some are battling away just like TP described (after they’ve had an evaluation) .
I’m a parent so I’ll go there but not easily: I caution you to not use depression/anxiety as the vehicle for your departure. I don’t doubt ( for a minute) what you’re feeling is real but you need to be incredibly truthful with yourself and others- especially your parents. If there’s an overriding concern about how your departure will look to college admissions … that’s a red flag to me. If you were my kid- college would be the last thing on my mind.
If a rotten roommate was just cause to leave a school- most dorms would be empty. And - if an adult ( or nurse ) on campus thought you were at risk- you would have been home by now and seeing a specialist. Growing up isn’t meant to be comfortable (even in a cocoon- like setting like BS ) - Adversity is never pleasant but it helps us grow and thrive. Too many teens throw around depression, bipolar or anxiety… without understanding what these medical conditions truly are. Make sure you’re not doing this just because you want a better school experience or a ticket home.
I’ll just leave you with this: There is no greater feeling than crossing the finish line and turning back to see all the people who have supported you along the way. Make no mistake- they will be there.
I wish you (and your family) the very best. Now is the time to reach out and get the help you need. Your school situation will take care of itself.
