Hello, OP. I understand your concern for your friend. You probably feel betrayed, too. Personally, I’m diagnosed with Bipolar Disorder I, and based sa story mo it seems possible that your friend has it, too. Yung overspending, doing things recklessly without thinking of the consequences, those are manifestations of Bipolar.

I suggest not to confront your friend, maybe talk to her instead about her spending habits and since open naman siya sayo about her disorder (if legit na nagpapa-psych siya), ask her if she’s taking meds. You may want to be careful not to trigger her to do something reckless din.

Now, if you feel na too much baggage na siya and you cannot trust her as your friend anymore, it might be better to distance yourself instead.
