@Faith-and-Hope it isn't a matter of me being comfortable calling the HC, it is a matter of me being allowed to call the HC. My muddle is far more muddled than anyone here knows and it puts a strain on...well...anybody who comes near me really. That is why Forum Land generally works so well - there is a buffer between all of you and the bigness of my muddle.
Having said that, I have now spoken to someone from the HC and we have a plan going forward. As I knew would happen, a brief call has massively shifted everything. I knew I knew what I needed. It's just trying to get what I need that is the tricky bit. 
The storm is already starting to settle now. We have a plan. I feel much less alone for having actually spoken to someone. Super big thank you for "reading" stories to me @CheerBear. We need to put this in our toolkit. I super love both the crayon stories. You are right, the second one is extra funny. My favourite bit is the bit about the dog eating the crayon.
I only just started listening to the story about the rabbit when the next giant wave hit. I will listen to that one while I settle my big feelings a bit more so that I can then do the steps in the plan that the person and I came up with. Thank you for helping me keep my 100% success rate intact CheerBear. See, this DBT stuff does work! Thank you for being my DBT study buddy.
