Hello 
as long as you followed the instructions then no need to worry about getting it “right”, it is already done.
Sounds like you are now in the hardest part which is letting go of lust for results. Let me guess, your mind is constantly worrying you with thoughts like “did it work?” and “when will I see the outcome?”
You need to let go of this. I know it’s so much easier said than done.
First things first – I wrote a post about this here that you might find helpful:
Second – when you think about the person, try and move your mind away from possessive thoughts. Things like “they are mine, I must have them (back)”. When you worry or obsess too much about a situation and the “how” and “when”, you are simply getting in your own way; freezing the pipeline so the water of change can’t move through it, becoming a “hostile observer”.
When you think about the person – instead of obsessing about having them, remind yourself that it is already done, and then use your mind to clear the path. Simply project loving, warm, empathetic thoughts at them with no thought of reciprocity. Don’t waste time wondering if they feel it or if they are thinking about you. Just project your love at them with no expectations. The more you do this the more you will train yourself to move away from obsessive/possessive thoughts.
The hardest part is patience. I wish you the best
