Sleepless

[heslopian]

It’s been said far too many times
The teddy isn’t comforting enough A wee bit girlish, but then that no doubt suits the character you're conveying here.
The blankets are cold
The bed too large
(it’s downsized and yet there’s still too much space)

I say everything too much because
I’m afraid
You’ll forget them if I pause What is "them"? I think you should be a bit more specific about what the character is saying.
Long enough to breathe

I’m tossing and turning
Restless in the grip of
Nightmares that mock me with your face
And your name on my lips as I’m released from
Hel I think you mean "hell." Also, do you really need enjambment here? I think it would work just as well next to "from."
And all her promises of half-dead romance Who's "her"? Are you personifying hell as a woman? Again you need more detail here.

I say things too much because
I’m scared
I’ll forget how to express
Everything Is "Everything" needed? Would it work better as a three line stanza, ending thusly: "I'll forget how to express myself"?

It’s been said far too many times Is "far" needed? This could just be me; I'm a fervent believer in economy of words.
You make the bad things go away
The nights are perfect
The time endless
(if only I could stop it when we needed to… all the time) This last line needs more detail. The more I think about it the less it makes sense.

I say things too much because
I don’t know
How to say them
‘Just enough’ Would "Just right" work better?

Time and distance are one and the same
And you’re far too long away from me Excellent couplet. For me the poem should end here.
For anything to be comfortable in this
Un-dead dream that
Threatens my reality

(did you know you keep me real?)

All this is just my opinion, of course. The poem has promise but it needs to be tighter and a tad more focused. Think hard about your structure and what exactly it is you're trying to say. Thank you for the read, Mrs-Sin
