What to do? Distancing yourself would help. Yes, they provide for you but as you say, is it enough? You do not feel emotionally cared for.

At the same time, moving out and being on your own could indeed trigger your depression. So you would be trading one 'problem' with another. IF you want to move out, make sure you have a support network. It would be useful to have mental health support to help you through this journey too i.e. counselling.
