When we just sit with our feelings and bodily sensations in meditation, we don’t have to understand or fix them. We just have to watch them. With equanimity and awareness they reveal themselves as they are.
With mindfulness we realize that those feelings, like everything else, are impermanent. They will pass. Right now, it may be like this, but in time how you feel now will change. In the mean time just practice cultivating loving awareness. Don’t judge yourself or add to the narrative with every thought that arises.
