I agree with Angela G TX. I was about to give the same answer - Catholic Charities, and the person does not need to be Catholic!
NAMI has support groups, which can be a nice addition, but it is not therapy.
CC offers therapy with psychology students or an LCSW (therapists that are often better than psychologists), or students doing their practicums with oversight, on their way to obtaining their licensing.
CC often offers various modalities of treatment including CBT and sometimes even EMDR (excellent for traumas).
If CC feels they cannot help the person they will probably refer that individual to a group or person that can.
If they feel that the person requires medical attention (sometimes what we think is "psychological" or "mental" is very much a biological/medical issue), they will probably advise medical care. Unfortunately, if doctors THINK it is "mental" the patient often will not get the appropriate medical testing and care (our family went through that).
