Dont worry the wounds wont heal

When Iam in a situation,
Maybe like this,
Where youre yelling at me,
Throwing things- trying not to miss,
You really dont know,
How much Iam itching,
To touch my wrist,
A slit,
Maybe two,
I just want to make sure,
That this time,
I wont wake up from the floor,
And if I do,
You know I will try again,
In till one day I reach the end.
