your mental health wasn't always the best. you had suffered from depression, anxiety and especially bpd.

price knew about your mental health and how low it could get, especially after awful and intense missions that caused you to lose comrades.

you and price came back from an intense mission that had almost resulted in him dying, which had ticked your mental health completely.

you began to go off on him badly, telling him how horrible he was on the mission and that you're extremely disappointed in him since he wasn't careful with his own actions, let alone his own life.

after a while, you went back into his office to apologize, almost close to breaking down hoping he did not hate you for having your flare-up and immediately blaming him for the mission going almost very wrong.
