You acknowledge to yourself that you are in pain, you are hurting, and you be very gentle and compassionate in taking care of yourself.
You are hurting. This emotional pain is very present and very real.
How do you take care of someone who is hurting? Make them a cup of tea, comfort them, be with them, speak softly and compassionately with them, don't push them beyond their limits of coping, help them feel safe and calm.
What things comfort you? For me it is hot coffee, warm scents, soft blankets, gentle music, things like that. What comforts you? Allow yourself to have it feel it sit with it.
You are hurting. Nurture you. Take care of you. Your pain is real.
