Was han ever specific about what she has? Like a heart condition or sum??

Tbh that's what I like to know..like if she has smthin' very serious medical issues, she'll atleast hint ppl, i mean that way she'll get less hate,and if the condition is serious then i don't think one month of break will be enough!!(I mean if u r just writing that it's cuz of personal reasons ppl ought to think it's some kinda excuse) Dk much tho..my opinion only
