Well, your piece here definitely has potential. It's in paragraph format, which throws me off ... big time! I'm not sure about that? Parts of the piece don't quite make sense to me, they're not written out right and have fragments and stuff all throughout. I'm going to show you (in POEm format) how to correct the piece. I think once the english is worked out in it then you'll do okay in paragraph, prose, or poem format.

Here it goes:

My ghost of the PAST pain
comes to hurt me with the bad I've done.
- Now, with this I want to mention the second line. It doesn't make sense to me. I guess it does, but it's not poetic. In prose/paragraph form you'd have a good sentence but if you're going to do poet form, I'd try;
"The ghost of my past pains
has come to renew the bad I've done"
(or something like that)

The ghost flies over me,
I'm afraid to touch it
for it may kill me.

I sit in my room in a ball,
I just want to escape.
The pain comes so fast,
with the THOUGHT of my past,
REMINDERS OF HURT FRIENDS,
AND why people HATED me.

Pain I felt years before -
How could one ghost
bring so much pain?

I've thought about this stuff,
it never really hurt me
AS IT DOES RIGHT NOW.

I want this ghost to part
taking his thoughts with him.
I stand up to touch,
but the ghost screams in horror.

He flies, I stand and look
He moves swiftly,
and I'm filled with joy ...
knowing he'll never come back.

The poems not hardly poetic. I'd say make it a prose instead. Which is just like a few short paragraphs and such. But, this way it's easier to see the changes I made grammar wise
