Edgar Allen Poe: crazy or normal

Was Poe a phyco mad man, or a normal  person? I believe that he could have been a normal, but I think he was mentally disturbed. I understand he was disturbed because his mother, foster mother, and wife all died of the same disease which would drive any one insane. Poe wrote creepy,disturbing stories and poems that he might have wrote because he was so upset over the deaths of his loved ones. Just because someone does something disturbing does not mean you can judge them as crazy. They might just be expressing their feelings and ideas about the world.
