Hi Vineeto,
A question if I could please 
because this is the exact place where I have hit a wall in the past without any clear way how to proceed :
Basically looking at those ebbs and flows yesterday and today… it is a weird situation because I cannot find any particular beliefs, values, fantasies etc which are attached to the feelings, in fact I don’t think there are any. They seem to be purely habitual at this point.
Perhaps there were some beliefs around these feelings in the past but it seems that they have kind of become automated at this point, in that even in the absence of the belief the habitual feeling persists. So looking at the gloomy feelings yesterday evening there was a few which were connected to each other but they were not related to any beliefs or values. It was varying feelings of despair, panic and insecurity. They would be triggered periodically like a case of chronic back pain and would bounce from one to the other. But they have no rhyme of reason to them, there is the habitual feeling triggered by association and that is it.
So how does one go about tackling these kinds of habituated feeling patterns? They are quite sticky in that when they come they have this ability to compel and yet at the same time I can see they are over nothing substantial. It’s like ‘I’ am not done with ‘being’ that feeling yet although ‘I’ have no ‘good reason’ for it other than habit. I could trace them to an event or thought, but other than that there was nothing more in terms of any social identity aspects which were behind it, just habitual feelings. It’s like someone flinching at the sight of a stick if they have been hit with one enough times.
What it seems like to me, is that the best way to approach these is to continue to experience them fully without moving in either direction, and when I do this usually within some short time the feeling is indeed exposed as just a habituated affective pattern. Then some time down the line it repeats again, just by sheer force of habit, but it does seem like that habit is being chipped away at each time I experience the feeling fully, see it for what it is and get back to feeling good.
