Has anyone had a similar situation? What would or what has your Psychologist do/did or required to do in this situation:

A few months ago I may have been considering an accidental overdose on something Im allergic to. I didn't actually do it and felt stupid for even thinking of it. I didn't try anything else and tried to push it out of my mind. I was afraid to tell him do to a recent suicide in the family, I didn't want him to think I was going to because of that. Im not going to do anything and im embarrassed by the whole thing. Im not normally like that.
I don't want to make more out of it than needs to be and I have hear stories of people getting put in hospitals and stuff for things like this and I don't think that is necessary but I am afraid of the risk since I don't know what they would do for something like this.
Has anyone ben in a similar situation? what was the result, I didn't act on it if that clarifies.
Thanks
