+[00:13.85]Without escape, I ponder
+[00:15.98]A million questions
+[00:17.25]I don't need to find an answer for
+[00:20.59]Like, is it worth the hassle?
+[00:22.78]Or, is it worth the pain?
+[00:24.23]Look inside the mirror and say to myself
+[00:28.17]Am I enough?
+[00:30.81]Oh, am I worth it?
+[00:35.570]
+[00:37.670]I see the way you notice
+[00:39.980]All of my fragile moments
+[00:42.210]A part of me is still uncertain I should let you in
+[00:46.670]But as it flows and passes
+[00:48.800]The time will just confirm
+[00:50.150]That when you're here with me
+[00:51.940]I can just let go
+[00:54.560]Now suddenly, the clouds clear out
+[00:59.070]All my worries disappear
+[01:01.070]And all the stars, they feel so near

+[01:36.630]A sort of, kind of healing
+[01:38.980]A different wave of love that travels
+[01:41.530]Through your precious words
+[01:43.370]At times, I circle back, but
+[01:45.600]I guess I just forget
