+[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
+[01:03.340]I could almost reach out right now
+[01:07.580]Because of you, feel myself again
+[01:11.980]You helped me realize what was here to do
+[01:16.480]Because of you, I'm feeling real again
+[01:20.840]Now I know where I should go
+[01:22.940]You got me walking back to hope
+[01:25.090]One step at a time
+[01:34.560]I can't explain the feeling
+[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
+[01:46.980]That when I'm down and low
+[01:48.940]I could count on you
+[01:51.460]Now suddenly, the clouds clear out
+[01:55.760]All my worries disappear
+[01:57.810]And all the stars, they feel so near
+[02:00.300]I could almost reach out right now

+[02:41.030]What can I say but thank you
+[02:43.400]Surrounded by some angels
+[02:45.190]Honestly, it's hard for me to live without
+[02:49.800]Tomorrow's bringing something new
