I'm sorry you're struggling

I know you've been in pain for a long time
In a sense I can relate, I change my mind a lot too.... I do not trust the professionals after some appalling experiences, and I am no longer young
I was thinking, maybe if you are open and honest, and "strong" and "insistent" (I know you have the "ability" to be all these things, as all of us do) the care coordinator may get things moving in the "right" direction and decide that you DO "meet the criteria" for DBT, STEPPS, or some other adequate and effective help. Don't wait until you're "old" like me before insisting on adequate care
PS I've observed so many posts over the years, from people in the UK, asking WHAT do they want before they offer help that actually helps. Do they want us dead first ?

(I'm sorry for the triggering thought, it makes me so angry how some of these professionals behave
It sounds like you have someone "good" working for you. Remember, we employ them and DEMAND that they help - not "hospital" again and new meds ...something that has been "proven" to be more effective...
