I feel like a stalker when it comes to you
Always looking for that slight glance
I slap myself just to make sure this is true
All I want is just one chance...

^ I really like what you're trying to say here, that you are very interested in the person and that you're willing to show that interest by paying a lot of attention. I have to admit that I do not like the words "stalker" and "slap" because they seem to be too harsh for the rest of this stanza. I'd prefer something that'd be a bit smoother, but still has the same effect.

You were there when my world crashed
Helped me to pick up the pieces of my heart
Healed the pride that was smashed
You're the reason why I can restart...

^ I think the speakers feelings are now reasonable and I can understand them. I like that you first told how you felt about the person and now you're telling the reasons, that helps the reader to follow your thoughts as this poem developes.

I don't know what you did to me
You gave me hope to love again
In a short time, I escaped reality
In a short time, I got rid of pain...

^ The message of this stanza is really powerful, because it shows that love can't be explained and that it will be able to get over the bad times and move on. You worded this really well and I actually like the use of repetition here.

You gave me a reason to believe
That there is still a girl I can trust
Oh how my heart feels relieved
You've covered me with your angel dust....

^ This was actually my favorite part because it's so full of hope and love for the person, who filled you with love again and I liked how you used "angel dust", I was actually waiting for it.

Overall I think this is a well written poem, that is filled with emotions and I like flow and rhymes.

Your rhyme and theme are fine but I can't find the rhythm/metre of your work. IMO poetry needs to flowwith a rhytm like in a music piece.
