No matter how much i try 
To touch your heart 
Its useless 
If you do not desire  

Sometimes you realise 
(That) when you lose 
Love is nearby 
Keep it while you can 
Before it is too late 

I dont blame you 
I was blinded 
Could not see 
You were the one 

I gotta live 
With this wound 
That is within my heart now 

It will heal 
Time, goodbye, time 
Like (time) before 
But till then 
IM NOT OK.

Pretty good poem — I like it as it is quite smooth and thoughtful, evoking a sense of deep emotions and the turbulence of life. On the structure.  There is one correction in orange, and the words in green are just poetic additions of style, which you, the artist can consider if you want them. It is your call... Wish you the best in your English learning!

Im not ok

No matter how much i try
To touch your heart
Its useless
If you dont want

Sometimes you realise
When you lose
Love is nearby
Keep it while you can
Before it is too late

I dont blame you
I was blinded
Couldnt see
You were the one

I gotta live
With this wound
In my heart now

It will heal
Time by time
Like before
But till then
IM NOT OK.
