There are levels of hell i am sure...
Thinking back to during my worst times ( always the romantic relationships which luckily i have avoided for a long time now) i always sweated the small stuff...there was nothing i could do, no matter how hard i tried. Its obviously important to you Tery, whatever your fretting about.
General anxiety to me is those mildly annoying thoughts that float by, that dont have the strenght of the emotion of dread or terror in them. i can cope with those. Those we can do something about. but in the worst kind of hell we all cope differently. I used to go through multiple scenarios extremeley tense and agitated. Looking abck i wish i would have taken some medication...i wonder how i came across to others...hmmm
We are going through a big change at the moment and there's not much 'control' to be had and things just keeps going wrong before going right. You do all you need to do and for the rest, all you can do is place your trust in the Lord.
Then there's the 'scenario thinking' you speak of, it's irrational, out of place and has no reason for existence, yet there's nothing you can seemingly do to stop it. I used to pace up and down muttering to myself, trying desperately to get the thoughts to leave me be but as soon as I took a breath, they'd find a way back. The medication has given me room to breath and have the presence of mind to see when things are turning into irrational fears and to actually put a stop to them. Were it not for the medication, I'd be in a seriously bad place right now.
