I was asked if I had any active plans for suicide, and I said no, should I have told him the truth lol...?
I don't want to tell you if you should or not, but know that therapists are mandated reporters™ so they will send you to the hospital if they think you will ctb.
Sometimes some therapists don't get the difference between wanting to ctb and actually planning to ctb.
In my experience, telling therapists that I have a set plan will get me sent to the hospital 100% of the time and I can't bullshit my way out because the authorities trust the therapist over me. But I usually just tell them when I don't give a shit about what happens to me anymore and could use hospitalization as more fuel to ctb.
But saying that you feel suicidal or have suicidal idealation is a hit or miss if you don't want to be hospitalized. It really depends on the therapist.
So in a nutshell, saying that you do have a plan for ctb will get you hospitalized, but saying you feel suicidal won't guarantee hospitalization. It's actually part of their job policy to report, and if they don't, they can lose their job.
So if you do want to tell the truth, just know that you will most likely get hospitalized depending on how high you are on the ctb risk scale. Just something to keep in mind.
