Looking for support

We are looking for support regarding on how to convice our mom to let us go on testoserone (being nonbinary and AFAB, assigned female at birth), as that's something we want (and she's not being very supportive). We also would like support regarding feeling unhappy at a residental therauptic boarding school, as it's making us suffer (we refer to we and us because we're a system - multiple people in one body here). We would also like support regarding having to break up a romantic relationship because the treatment center forced us to and we still have affectionafe feelings towards the other party, yet we can't even be in the same room as each other due to the treatment center and their actions nor talk to each other. It is heartbreaking and we need suggestions on how to better cope with all of this.
