Bring to mind someone you find it very, very easy to wish good things for. A grandchild, a close friend, an old friend -- or perhaps even your childhood dog.
Think of them, and reflect on the struggles they're facing or faced. Reflect on how much you want to hold their experience, how much you want to hold their heart and be with them. Imagine how they look, how they feel inside, when you're lovingly, gently, selflessly holding whatever pains or grief they may be experiencing. Take a few moments to stay with this; feel, as best you can, how your own heart as you do this.
Now, think of how they regard you. Wouldn't they wish the same for you? If they knew what your experience was, to your deepest depths, wouldn't they want to hold your heart, too? Allow yourself to receive that holding. If it's hard for you to imagine receiving it from a person or a pet, receive it from Jesus, or Mary, or Tara, or whatever being is great enough to hold your heart.
They are closer than close to you. Feel that holding. Feel the light of their deepest being holding whatever in you feels heavy, dark, painful. Stay with this reflection as long as you like.
