Recognise your triggers of shame. This is the first step to being able overcome shame.
There are no universal triggers of shame. This is personal to to everyone and dependent on past experiences.
Defining what shame means to you allows you to take a step closer to being more aware of yourself. This can help you over time to practice how you response to shame, rather than letting automatic non-helpful impulses take over.
The one antidote to shame is empathy.
Being able to relate with others who can empathise with what we're feeling, without judgement, helps us overcome our shame.
Be vulnerable with others and seek empathy. This may be the last thing you want to do because shame can trigger anger as an automatic emotional response.
Pointing the finger and blame at others that have caused us hurt gives us the illusion of control and helps us avoid confronting our own feelings.
Anger is not in itself negative - just don't use it to avoid / cover up deeper feelings.
