Is Enthusiasm the opposite of Depression

Is Enthusiasm the opposite of Depression
Thinking about writing this blog last night, and this morning on television I heard 1 in 5 People suffer from depression. That number is shocking! I had no idea that many people are affected by depression.
Unaware of what depression could do to someone, I have now seen it first hand. It is like an infection that spreads ever so slowly or also at a rapidly pace. But if not treated, it can consume an individual and cause them to give up on life. What a horrible feeling of helplessness.
I was curious as to what the opposite of depressed would be. My first thought was enthusiasm, and after looking up the original meaning it seems that to be enthusiastic is to be possessed by the God’s. I love that thought and get it, but at the same time I find it hard to believe that people who are depressed “don’t have God in their lives
Wondering what others thought the opposite of depressed may be I posted on my face book status “What One Word is the opposite of depressed.” I received several one word post, while many people related the opposite of depressed to God, religion, faith, and various other words relating to our inner spirit of happiness.” Therefore maybe I was correct and the word Enthusiasm is the opposite.
When you are enthused about something it inhabits your surroundings and environment. Your enthusiasm might even become contagious. On the other side if one stops being enthusiastic, does that mean they become depressed.
If Enthusiasm is contagious, does that mean depression also can be contagious? Well I’ll hold that thought for another blog.
