One might argue that if someone is appreciated on the basis of whether that person makes one feel good in the moment - they are being treated no different than a drug (alcohol, etc). Some argue that such unhealthy dependencies on soothing agents (drugs or people) stems from lack of self soothing skills. Apparently, most "happy healthy people" (there are ofc caveats with this definition but for arguments sake let's assume that we share some understanding of what that means) have an intuitive understanding of how to take care of themselves both physically and emotionally in ways that return them to a baseline state of sorts. If you lack such skills, you often resort to less healthy coping strategies to draw yourself towards this baseline state.
Funny quote from sir Terry Pratchett: Death: "THERE ARE BETTER THINGS IN THE WORLD THAN ALCOHOL, ALBERT." Albert: "Oh, yes, sir. But alcohol sort of compensates for not getting them."
