Where do I find my joy?

A text from someone I used to find great joy in. I wasn't expecting it so at first my heart wants to be excited or happy...to feel some positive feeling. But I immediately turned to worship. To singing about who God is and that He is for me. I don't want to put any of my joy or happiness in hearing from this person. Or any person...or any hope for the future other than hope in my Father's plan. The only one who will never leave, never forsake, never break a promise, never change His mind, never turn away...is my Lord. The only one truly safe to trust is Him. My heart is fragile right now especially. I can't survive and find joy in anything else. Because everything else will disappear at some point. Only my Father stays forever.
