well she has like a super long history of emotional abuse and manipulation from a relationship she was in. so i know she sees someone about that, probably at least once a month at this point, though it's after effects are very ongoing to this day. so there's that. i just don't know how much that falls under cecilia's specialization. also in the past cate found someone for couples counseling with her ex - but they either never went or only went one time and that was also a mess.
the last idea is that she works for a basic skills therapist part of the time and has a couple of kids she works with who are from high risk living situations so one of cate's kids/their family could be one of her patients, maybe.
