here's what's logical.
her son recently died in HER hospital room from DRUG issues.
she used trimspa, lost an amount of weight that wasn't too unusual for those drugs, however in the period of time that she did lose weight was highly unhealthy.
my best bet is she died because of a heart issue, which can also lead to lung issues because of lung swelling, because of a lack of oxygen in the body.
or maybe she overdosed on something.
but i think my heart theory works.
