AIO for this conversation with my boyfriend

I usually don’t have acne but right now I do have three different noticeable red marks on my face from me picking pimples that were there. So we’re laying in bed and I’m not talking about it or anything and he randomly goes you need to do three things ~stop drinking soda, picking your face, and stressing ~ idk maybe I am overreacting I just feel like it was an unnecessary comment to make out of the blue when I wasn’t even saying anything?
