Yes, but this can be dependent on factors, depends, if brain wise, maybe not, as I finally accept not everything is the enemy or God teaching us a lesson or sin.
For instance some Christians might get cancer, not sinned one bit, in any major way, obey God, fight satan and have no bitterness and forgive and everything, pray, the lot.
However they did not eat right, or healthy, or ate things that might, like Aspartame in chewing gum and soft drinks cause cancer perhaps.
Point is for some, like me, if sun shining and spring and nice, just right for me weather, I can go cycling and golf, etc.
Feel good.
Another day I might be tired, might be in work and have someone, even if jokingly, meaning did not mean it that nastily, say something I get down, rejected, run to my sin for comfort, gives me guilt, fear of God, I'm a Christian, should not be doing that, might go to hell when I die, etc.
Then depression, etc.
I find, and like adventure, so long as does not really effect me, trouble is, it always affects someone, like recent deaths and injuries in the recent UK snow falls.
But for me, suppose it gives me something, action stations, battle the snow, turn on the water punps as heavy rain comes to avoid flooding of gardens from and back.
Watch live news in the US for hurricanes and whatever else:

I become serious me, no time to get down, depressed I'm occupied.
Boredom another big factor.
One reason in this small like Christian booklet I recall, think it said in the struggling with lust section, keep busy.
It's true, boredom, not doing things for God, not having a mission often leads us to sin, or get down, depressed, upset, dwell on things, think too much, so on.
Which probably explains why I feed off the excitement, some fear of those events I described above, unless too much at once happens, then I get to start to worry and maybe feel a panic like attack might be possible, which I have to block.
So go through the above list, check, I would say, please, please keep a diary, and when you have a good day, note things down as you go along, unless you have a good memory.
So for example, sunny today and got a chance to go out and spend some money shopping that I saved up to treat myself to that.....
Today I feel so lonely and depressed, the weather is cold and overcast and grey and someone just snapped at me for no reason on the forum, I didn't even do anything, probably not me, just in a bad news, but only made me feel worse.
We see the difference, first sunny, getting out, fresh air, spending bit of money, treating yourself, alive, free.
Second situation we see dull day, depressing in itself, feel hemmed in, can't go out, cold, miserable, someone, the enemy worked through, without them knowing it, snapped and had a go at you, upset you, playing on your mind.
I think from that you can see a pattern.
If none of that, may be drugs and I HATE to say that as imbalance in the brain somewhere, etc.
Anyway, hope that helps some, blessings, Lee.
