Um, it’s a difficult one. Speaking from experience, bottling up your issues is never a good idea, as it can/will lead to further issues down the line. I would talk to your drama teacher about your problems, as she seems to genuinely care about your well being. If you do end up being sectioned, which would take a lot, it could lead to you getting better, who knows. Regardless, you should talk to someone about your issues, that alone may help things
