drugs, perscriptions, depression

See a doctor to find out if it is true. Our loved ones often notice things before we are aware of them. Maybe your husband is noticing changes in your day to day personality or behavior that have him concerned. It would not hurt to have it checked out. At least, if all is well, you can then tell him maybe HE needs to be checked out as you are fine. (I'm an R.N.)

get a second opinion. see a therapist.
