Hello
Welcome to Pherotalk 
I am sorry for the troubles you have been going through. The men above have given you great advice. Just keep in mind that in life people come and people go and we all make mistakes and the most important part is that you have learned from those mistakes. Our mistakes and triumphs are what shape us as individuals.
Sending a letter with mones on it will not have the effect your hoping for unless you have been wearing those mones for a while in her presense. She will not associate the smell or feeling to you.
You will need to wear them in her presense and even if you do they can not change a persons free will.
Read this link to get a ideal as to what mones can do for you.
That being said, you mention wanting something to make you braver. I am assuming its confidence your really looking for. I suggest you look into Ishine, IO and AMMO
If you have any questions just ask.
Your GC will be in your email box shortly
