It’s about acknowledging your feelings and increasing your ability to cope with discomfort and trust that you will not be damaged by it. It’s about noticing when you’re ruminating and obsessing and fixating on things that you can’t change (the past, other people, etc) and pulling back from the intensity of those thoughts and allowing yourself to name the feelings.
See if you can separate the feelings themselves from the ‘story’.
So, you pull back from the thoughts ‘why did they do that? Why does everyone always abandon me?’ and instead notice how your body feels, notice your emotional state. Don’t try to ‘solve’ it through distraction or cognitive problem solving or assigning blame. But recognise ‘I feel angry’ or ‘I feel lonely’ or ‘my heart aches’. And just stay with noticing things on that level.
It takes a lot of practice, but it does really help
Reframing thoughts is really about noticing your habitual interpretations of things, and opening your mind to different interpretations. If the sense you make of life events tends to go a certain way, it becomes a self-fulfilling prophecy E.g. if you tend to think ‘X always happens to me’ then you will work less hard towards a different outcome - because what’s the point? Or if you tend to think ‘everything is always my fault’ then you won’t recognise when someone is exploiting you or treating you badly. So it’s important to recognise your habitual interpretations of life events and practise considering different ones. (This becomes much easier when you are more specifically aware of what you’re feeling, thanks to ‘sitting with your feelings’.
Many people just feel ‘bad’ and turn their attention away before they can recognise whether ‘bad’ is ‘angry’ or ‘sad’ or ‘scared’ or what. Sitting with the feelings helps you begin to differentiate between them, and this gives you important information.
