Sometimes things are too big to accept all at once. When this happens, you can accept things in layers. (these things can be current or past stresses/life events)
The key to this is to accept whatever comes up (pain, emotions, thoughts) as it comes up without the expectation that this acceptance will be a cure for all of your ails. There will often be another layer.
Emotions can have a corresponding physical pain. Sometimes it is easier to AAA the physical pain first – this can help make it easier to be with and AAA the underlying emotion.
Everyone’s layer cake is a unique mix emotions and physical pain, Some people have more emotions and others more physical pain. Do your best to AAA whatever comes up. Also be sure to give yourself grace if you are unable to accept something- you will probably get another chance soon.
