Instructions
First, try to observe how you feel right now. Observe how your body feels and try to notice what emotion is prevalent right now. It doesn't have to be very intense. Although you will eventually apply this skill in the situations where you feel overwhelming emotions, first you can get familiar with these steps when you feel relatively okay.
Step One: Acknowledging
The first step is to simply acknowledge the emotion that you are experiencing right now, without judging it. Just put a name on whatever you are feeling right now. If you feel sad, then just repeat that sentence to yourself without getting lost in the self-deprecating train of thought. Instead of saying to yourself "I am always feeling sad, I am so weak and unworthy of anything because I can never pick myself up", simply acknowledge the fact that the emotion is there: "I am feeling sad."
Step Two: Allowing
This step focuses on reminding yourself that it is okay to experience any emotion. You are allowed to feel whatever you feel right now or in an overwhelming situation that makes you feel intense emotions.
Below are some statements that you can use to get in the headspace of allowing yourself to let the emotion be:
- It is okay to feel the way I do right now.
- I am allowed to experience this emotion.
- Allowing myself to feel this way doesn't mean that I am behaving accordingly.
- This will pass, but for now this emotion is here.
- This emotion is uncomfortable, but it won't hurt me.
Choose three of these statements (the ones that you like the best), and write them down in the worksheet. Next time you notice that you are judging your emotions, read these sentences out loud to remind yourself that you are allowing this process to happen.
Step Three: Understanding
The last step is meant to help you create a context for the emotion you are feeling. Many of us don't always stop to try and understand why we feel the way we feel. In this step, take your time to think about the past events that have led you to experience this particular emotion. Don't judge yourself, just think about the objective facts that formed the context you are in right now. If you say to yourself that "I was being stupid, and that created my feeling of anger" -those are not the facts, but you judging yourself. Instead, you could say "It is no surprise that I felt so angry, since I always think that people will abandon me if they don't return my call".
You can refer to the article about cognitive vulnerability. That one can help you build the skills to look at the bigger picture, instead of clinging to a negative opinion that you have about your experience.
Example
Step one: acknowledging - Right now I feel frustrated with myself.
Step two: allowing - This feels uncomfortable, but right now it is what it is.
Step three: understanding - I am frustrated with myself because I haven't cleaned my apartment in two weeks. I am not going to judge myself for this, because I've been feeling very lonely and mildly depressed. That's enough negative feelings, I don't need to make it harder on myself. For starters, today I will do the laundry.
Next Level: Working on Stronger Emotions
If you did the first part working on a relatively subtle emotion, you can further practice this skill thinking about a past event where you experienced overwhelming emotions. Think about how you would apply the same three steps from the first part, only now on a situation that was problematic for you.
For the first step, acknowledging, remind yourself of what you were feeling.
Then, imagine how you would apply the second step, allowing, to what you were feeling. What statement would you use?
Last, think about the bigger picture - what happened and what are the objective reasons for your emotions?

Thank you! This led to a break through for me. I now understand my motives and nature much better.
