She certainly appears to have difficulty regulating her emotions, good or bad. It is possible to express hurt without crying and anger/frustration without blowing up. We’ve seen a lot of crying. She got angry a few times and had difficulty communicating clearly and effectively. I think a number of things are behind her overflowing tears: anxiety, immaturity, and frustration are a few.

A more mature person would rightfully be angry with Miguel’s behavior, tone and frequent gaslighting comments. But, they would respond more like Krysten, with clear, concise, no nonsense, confident, assertive statements. They would be effective at navigating a disagreement to a healthy resolution, at least for her.

By crying all the time — because she seems to lose her ability to communicate effectively when upset, she ends up further fueling his gaslighting comments. I think she stumbles into tears or rage (which we haven’t seen but she threatens) far too easily.

I’d guess good therapy could help her with what looks like anxiety and work on communication techniques that would empower her.
