There are some psychologists that do not believe in medicating patients. They are of the opinion that all the person needs is to sort out their emotions and all will be well.
If the psychologist your husband is seeing is from this school of thought then he will probably not get any referral to a psychiatrist. Psychologists are not doctors and can not prescribe medication.
I think most people that have bipolar disorder do well to get medicated and achieve some level of stability and then seek a psychologist's help.
When you speak with your husband again try to convince him to see a psychiatrist with you. You can explain to him the psychiatrist will simply evaluate him and determine if medication is appropriate for him. He has nothing to lose in seeing a psychiatrist. Point out that excessive sleeping and his crying are both indications of depression. He clearly needs help.
Let us know how you are doing.
