Have you had a physical with complete lab work recently? If not I would say rule out anything physical like they round, hormones or vitamin deficiencies .

The stress of getting divorced is enough for anyone to forget things.

As for your benzo , yeah they can be hell to get off of.... But if the taper is done slow enough it's usually doable for most people.

In the middle of a divorce????? I don't think that I would taper off until the dust settled.

Take care
