Why/how did this upset my psych professor?

so today i met with my abnormal psych professor, who also to be a clinical psychologist. i was just talking to him about the cl and general coping techniques (it really meant a lot to me to come talk to him--he gave me an hour and 15 minutes of his time). but one weird moment during that meeting was when i was kinda implying something giving up and he was like "what do you mean? like, school, grades?" and i was like "yeahh, school, grades, life, stuff like that in general?" and he stared at me for like 30 seconds, and he was like "life? what do you mean life?"and then he goes "listen, you dont wanna go down that road with me" and course i had to clarify what i meant (i was talking more about cles when to know that, for example, a cl like physics is not your forte) but during this exchange in my mind i was like "oh wow, what did i just do?" obviously he probably thought i was implying suicide, but why did it upset him to that degree? did i completely screw myself up with him?
