Hello and thank you for contacting Just Answer:
Sorry that you are having a difficult time. You do not necessarily need to see a psychiatrist, but since your primary care has already tried paxil, it would probably be a good idea to see a specialist ( psychiatrist). I believe there is a mental health center at the Concord Hospital or you may want to try the group-Womankind Counseling,(NNN) NNN-NNNN I would recommend getting some support for yourself in the form of psychotherapy as well. The Alzheimers association also offers support groups for caregivers that may be helpful to you.
It would also be a good idea to get some in home support to help assist you with your husband, if you do not already have some. He may also benefit from some psychiatric care to help with his agitation.
I hope this helps and wish you luck.
