Before I started therapy for myself I wouldn't have understood (though I would have tried). I tried to cut back to once a fortnight recently due to financial concerns, and I ended up in a very bad place. I wasn't ready to lose the support. Losing something so important to me because of something like money, was impossible for that really sad, wounded, vulnerable part of me to understand. For people who haven't lacked that consistency or stability, and then gained it through a therapy relationship, it's so difficult to understand. Before therapy I really had no concept of it. Now I understand.
