Sorry for being late to the party!
I love the last line! I would recommend adding punctuation to the poem for clarity, possibly like this (for example), but how exactly you punctuate all depends on how you want to connect and break the thoughts:
I’m drowning in a sea of anxiety.
Wind mutes his voice.
Focused on my problems,
I miss his outstretched hand.
He calms the sea instead.
In general, it’s helpful to use commas, periods, and line breaks to keep the meaning clear in freeform. Otherwise it all starts to run together and the reader won’t know which phrases go with which thought.
