I've experienced similar reactions in how you can trigger others in what seems like a healthy way. I'd just say to make sure that you are not seeing yourself as a Healer to take on the pain of others unless that's that path you feel drawn to. It can be easier to instead see your being as a door to help facilitate growth in others, kinda as a spark or rerouting of energy to whatever one wants to call it.
Having a practice of centering your energy does wonders, as does understanding the fields that you may have extending from your physical body. Being able to pull back energy that may be too expansive will help, as will regular grounding.
Good luck, and hopefully your interaction helped him process what was weighing heavy.
