心软致病情深致命

Translates to 'Soft hearted leading to illness deep and fatal'. Here, it portrays vulnerability caused by strong emotions (usually affection) which leads to mental/emotional health problems severe enough to endanger life metaphorically speaking. Typically used in describing dramatic scenarios where feelings run too deep, especially romantic or familial relations affecting physical health and overall well-being, indicating how much impact emotional sensitivity can have when improperly channeled or overwhelmed.
