I don't think that discussing a fear of ODing regarding you starting meds would wind up in a forced trip to the hospital. In my experience (and this is coming from someone who has been inpatient 4 times) a trip to the hospital comes from suicidal ideation with a plan, and/or that you will not or cannot keep yourself safe. That and/or you've already acted on a plan. I mean, I don't know what the involuntary process is in your state, but that's how it goes down here. I mean, you should be able to feel like you can discuss your fears with your T without having to worry that they're going to lock you up. They will probably ask you if you feel like you need to go to the hospital and, if you say no, they will ask you what plan you will have in place to keep yourself safe.
