Lots of good advice here…you are early in the game, so to speak. Joining an organization/club may help a lot. Also seek out the “student listeners” (or similar title) the kids that have some training to help students who are stressed and unhappy. I’d go beyond your advisor to seek adult assistance…maybe a dean to help get you the resources you need,
You are not alone there. There are plenty of students who would hear your story and reach out immediately. You just need help finding them.
Keep talking to your parents and let them know if it isn’t better (assuming you keep reaching out at school) in the spring you will be leaving at the end of the year. Even having that “agreement” might make you feel much better.
And you are not alone here on this message board. Keep us posted. We wish you happiness.
