psychotherapy, counselling, psychoanalysis and sessions with clinical psycholoist can be so valuable.
GP's can choose to refer you to any of these.
Also your PD nurse specialist and neurologist could refer you.
If you are experiencing suicidial ideas then you could phone the local Samaritans, some also offer one to one counselling in their offices.
Please don't feel shy - get the help you need, it is so important and, if the first therapist does not feel okay for you, then ask to be introduced to another.
Mindfulness meditation courses are also so special.
