Dear Boxseller,
First, I want to say that your boyfriend is very lucky in having such a supporter on his side.

Any major illness, especially something like CH which is incurable, horribly painful and causes major disruptions in one's daily life can lead to depression.

If I may suggest, even though the CH and depression appear to be related, I would recommend that they be treated as two illnesses.  A visit to a psychiatrist can help with the depression by having the doctor prescribe  anti-depressant medication if necessary.  A visit to a good neurologist can help with the CH and it would be best, in my opinion, to allow the doctors to speak with each other so that they are both aware of how he is doing and can make adjustments in his treatments that compliment each other.

Your love and support are most important and they will help him so that he doesn't feel alone and misunderstood.

Best wishes to you and your friend.

Sandra

Great news. As an episodic sufferer for nearly 20 years you do learn to manage them. I've found a mixture of Verapamil and O2 helps enourmously, and after 6 weeks it's back to normal, medication free, for another 14 months or so. I also do a lot of exercise during a cluster period as it increases oxygen in the blood, which helps enourmously as well.

Best of luck.
Chris
