Sometimes repeated images need to be expressed or made manifest in the world somehow ... through the arts ... writing, music, visual arts, maybe ... gardening ... or whatever speaks to you.
Closing them down usually has them come up in other more disturbing ways .. but finding ways to acknowledge them without necessarily directly acting on them ...
Over time .. I have found that many thoughts that used to plague me have subsided ... when I have managed a situation reasonably ... some still come back ... and recently I have just had to accept that I have obssessive tendencies ... and say to myself ... ah a new obssession ... and try and deal with that one ... ... usually though ... better out than in ...
take care @jamesle2015
