A classic symptom of depression as has already been mentioned.

I've been going through my own personal hell for 9 1/2 months and I'm surrounded by things that I usually take great pleasure from such as my partner, my dog, music, art and films which offer nothing at the moment which is hugely frustrating.

I know it will get better, after all I have been here before but I'm frightened as I've never had a low that has lasted this long.
