Apathy and lethargy, together with tremendous mood swings are the worst of the symptoms. If I can spot when the mood swings are about to hit, I can just about control them, but the other two are just a killer.
The dog in the picture is no longer with us - we adopted her aged 9 years old and looked after her till we lost her aged 15. She was very perceptive to my moods - we now have a very lively, very beautiful golden retriever who is now 9 months. He is now very in tune with my moods and is very affectionate when he senses that I am down.
A walk across the Ridgeway with him charging around ahead of me and thoroughly enjoying himself is enough to cheer me up no end.
My PD is under control but can still get very painful and dehabilitating at times - thats when I really need to see those big brown eyes.
