In my opinion, "just chatting" can either mean chat about the person's/your struggle in general and try to understand it better, or "just chat" about your lives in general and try to develop a friendship with the person.
Option 1: Even when you're not currently struggling it is important to develop a deeper understanding of what triggers you and coming up with different idea of how to overcome those triggers. Discussing your struggles and different scenario's and the other persons struggles and scenarios when they struggle can be useful to identify key triggers and what to stay away from, or how to fix it
Option 2: Like I mentioned in my previous response, it is important to have a sort of friendship with someone on GYE which will make it easier to talk to someone when you struggle. Just try talking to people as if you're meeting someone new. Get acquainted with them, talk to them about their life, what they're doing, their age, family, work, etc.
