There is something about some folks who are exceptionally creative in the arts. So many of the best of them had personal lives with personal problems on average that were disproportionately greater than the percentage of such problems in the general population. It is almost as if extreme creativity & a commitment to using it and stable personal life often take divergent paths. I doubt if anyone knows why.
A lot of literary critics/historians would aver that this is the theme of Tennyson's "Lady of Shalott." She sits in a tower, separated from the rest of humanity, weaving images she can only view through a mirror. The beauty of her art derives from her existence and observations from her unique perspective outside (and above) the society and world she is representing in her art. That is her curse.
When she defies the curse and tries to come down from the tower to join society, she dies and her art goes away.
