We all have our own vices when we are manic / hypomanic saucier, I just wanted to say that to remind you you are not alone

- no matter the vice.
I like to remind myself when I'm wondering whether or not to tell my therapist something - "She's pretty much heard this before"? Well, that's what I think.
Not that it makes things that I tell her any easier either and I feel the same angst as you do.
But you're so right when you say
She can't help me if I don't tell her the truth.
I wish for you that no matter what you decide to do in terms of disclosing or not disclosing, that it works out to be the best possible solution for you and your needs.
Let us know how you go.
