Why** can't I be happy?

Actually...
                 why can't I feel it?

                                                    I know I'm loved,
                                      but my mind can't comprehend it...

                                            My anxiety just screams
                                          "NOBODY LOVES YOU!"
                                        "YOU'LL LOSE THEM ALL!"
                               Maybe I should just push everyone away now
                                  and find comfort within these four walls.

                           Because it seems like If I have nothing left to lose
                 I'll no longer have to go through with this self mental abuse.

And these dreams will be the death of me.
Broken sleep &
relentless lethargy.
I'm out of control,
so I'm told.
I've slipped outside of my soul,
or so I'm told.
My nose runs consistently,
Yet I don't have a cold.
Now everything hurts,
and yet I feel so cold.
REM dream sequences;
play me on repeat.
play on repeat,
Everybody hurts too but they carry on,
Won't admit defeat.
Not me,
I bend under the pressure,
Malleable,
& then break what's,
Valuable.
I'm weak at the knees,
alieness in alloness of stress;
Please let me rest,
Stop stealing my shut eye by looking in to mine,
I walked the line,
But crossed it,
No going back now I think,
I shudder each time I blink.
And in dreams I believe I could be happy,
Or at least not so sad,
Wishing to feel those feelings
That I've predominately lacked.
Now in dreams I wait to see a GP
in reality,
So he can endorse these feelings into clarity,
Prescribe me patronisingly with 50mg of setraline;
"I'm sure alls not as bad as it seems"
He says so candidly,
Whilst I'm sat here,
can't even speak,
trapped at the mercy of these endorphinemachines.
