Their inability to receive you is not a reflection of your value.
Take the needed quiet time to reflect on who you really are.
You're loving. You're a gift. And you're solid. All those years of feeling insubstantial... but you've come so far. Remember.
(When you've experienced rejection from those you love the most, it is debilitating and can completely destabilize you. It takes time to gather yourself, to recall and re-own your worthiness, your greatness, and your strength, and to stand in it -- knowing that you are good, and precious and deserving of more. Be patient and extra gentle with yourself as you honestly cope with the pain and how it threw you. It may be a while before you feel like yourself and able to open yourself up to others...to again freely offer and fearlessly share your love.)
