I am so sorry you are going through this. As to your mother's actions, I am not going to wager a guess as to what her motivations are. I feel like anything I say may come off as excusing her actions and I really don't want to. You were made to feel unsafe during a time when you were vulnerable, and that is not ok.

The only kind of advice I would offer is, maybe it might be a good idea to revisit your thoughts on therapy. A professional trained in dealing wirh depression may be able to provide you with better support than your family or college. Other than that I would say try to create safe space for yourself. A place away from your house where you can be yourself.

Please keep sharing, I am sorry you aregoing through a hard time
