Great points above...

Pose this question to your mental healthcare provider. Ask them too what the goal is in doing so. Ask them if they feel this is achievable.

I too am leaning towards following through with this recommendation. If your mental health is sufficiently poor enough that it impacts your daily life then yes, it is bad enough to warrant treatment.

I spent a summer hospitalised several years ago. I am not saying it was pleasant but it was not that bad.
