The gift of feeling joy is part of our true nature. It's like the sunrise heralding in a brand new day. It's always darkest before the dawn, but joy does come in the morning. The Light brings a new awareness, things hidden are revealed, and you find that you are the light, rising like the sun to a higher consciousness. The Light of God is shrouded in each of us, waiting to shine out into the world. So all the darkness (our stuff) begins to clear away when we go within and listen, feeling the radiance of Divine Love gently burning off our dross.
May your day be filled with the joy of knowing that God never changed His mind about you. You are made perfect, whole in His image and likeness. So whatever the ego is telling you, don't believe it. Shine your Light and watch the whole vista be transformed as if by magic. Spirit is truth, immortal, supreme, unlike matter, that's perishable and mortal. You are spirit.
When I stop my ego chatter and still my mind, I find myself bathed in joy that touches the loftiest height of human and spiritual joy. Life itself is joy. As the Psalmist sings, "In thy presence is fullness of joy."
Enjoy your day with the Angels, and remember your true Identity as a holy child of God.
