Phobia & relatiionsh. Strongly recommend the phobic client see a therapist Certified in EMDR. This type of therapy is extremely effective with phobias. No ridiculous promises, but often my phobia clients are symptom free after 1-2 sessions. And that is without meds!
Autophobia. Is fear of isolation or being alone. As long as you are tolerant of added demands & care for the person, you should be ok.
