Maybe not so much that the topic is difficult per se, but saying this one thing - whatever it is - is really excruciating for some reason. It can be something like asking for a drink of water. Its not really technically a difficult topic, but it does relate to having needs, and thats what makes it excruciating. So doing the work for me was getting "normal" about a glass of water, for example. Being able to just ask for one. Being able to share this part of the human experience. Between weird italian manners and religious ideas about sacrifice, this IS a big thing for me. So this times a million other things.
