The OP hasn't commented again in a while, so not sure she'll see this, but here goes.
I do know what you're saying. My daughter will also tell me stressful things and my knee jerk reaction is to want to fix it. Also, it's just very stressful -- I feel my blood pressure rise(!). But... I try to do more listening than talking. I definitely do not try to solve her "issues." These moments are part of a much bigger picture. And while I sometimes think that DD tells me too much of the stress, I would never discourage her. These moments will end someday. Someday, I will be very old and maybe sick, and DD will treat me with kid gloves. For now, I want all of what she gives to our relationship.
