Best thing is to talk about it, gets it out in the open and daylight.
The big black dog doesn't like that and skulks away waiting for another chance.
Keep talking, keep it out in the open so others can help, and that will keep the black dog way from your door for longer and longer,but he will be lurking.
Be thankful for being able to have so much precious time with your wife and family,take every day as a gift from your god and treasure it and hold it dear.
Prepare yourself for the worst, BUT, never give up,work,plan,pray,hope for the best to happen and that will keep the black dog at bay too.
Keep up the talk with your doctor/friends/family it all helps to releave the stress, and who knows, a cure or time buying treatment may come along.
If you ever want to just have a chat give me a call or pm I'm here, sometimes fighting off the black dog myself
