I agreed to no mental illnesses, yes. Not just for Selena.
But being fat is not an illness. Not being able to use nicknames like Demoo Lofato and Adelephant is ridiculous. If those personally offend you for some reason, get rid of that subconscious in your head and go for a run and go on a diet. Stop glorifying obesity by saying "Stop bodyshaming!" It is unhealthy. Stop getting so butthurt over the SMALLEST THINGS. Get a grip.
