I think this is a very relateable poem. The rhymes don't seem forced, but are still a little amature. My earlier work is like that, it takes time. But the fact that you wrote it, means something. I think you should change the format of it. It is easier to read, gives it structure, and is more ellegant, and creative.
This is a good way to do it:

"Addiction is awful
I'm so full of doubt
withdrawal is something
I never took the time to think about.

I sit here trembling
seems I have the shakes
I need something to calm my nerves
I've had about all of this I can take.

I hide the pain inside
so very well
those closest to me don't even know
I'm going through this hell.

I'll just take another sleeping pill
to get me through the night
I just want to be normal
but I feel hopeless with no end in sight"

Also, capitalizing your I's is very important. Proper grammer and spelling is important to a lot of writers, and people will down rate if they see this. Try adding in some punctuation, like more commas and periods at the ends of sentences. It cleans up well.

5/5 for the story of the poem.

Nicely written... though i likes stanza better but still yours is a very captivating read...

"Addiction is awful im so full of doubt, withdrawal is something i never took the time to think about"
^^ these lines are so full of emotion...

word choice is great..

overall wonderful write..

Break the lines... break the lines please!
The poem itself is very good but please structure it properly. Concept and the lines are good. Enjoyable one.

Try penning it out like this...

Addiction is awful
im so full of doubt,
withdrawal is something
i never took the time to think about,

I sit here trembling
seems i have the shakes
I need something to calm my nerves
I've had about all of this i can take,

I hide the pain inside so very well
those closest to me don't even know
I'm going through this hell,
I'll just take another sleeping pill
to get me through the night

I just want to be normal
but i feel hopeless with no end in sight

Hope this helps... this is the way to break a poem up into stanza's. It allows the reader to read it more easily without taking away from the poem.

Overall a nice job...

I know you're not into writing in stanzas,
but YOUR RHYMING IS GREAT!
This poem would be enhanced so much if you would just put in the line breaks where you meant them to be!

Overall, very honest storytelling. I felt a real connection to the speaker, which is obviously the point of any poem. Good job, but please take my advice about the lines.

This poem is well written and as we say in rehab, admiting you are powerless to addiction is the first step to recovery

Wen i was addicted to alcohol and i finally quit i felt the same way as the poem. another great poem. the rhyming is good and u can actually feel the pain

Wow. I know this feeling far too well. This poem is so relatable. You expressed your emotions so well. I sort of like this layout instead of the typical, cause i get the feeling you're writing from the heart. I really enjoyed reading this. Well done :) 5/5
