I am sorry that you feel that you lost a friend.....times are tough for a lot of people and maybe something happened and she can't afford to send you money.....maybe if you could pm her or leave a message that the money isn't the issue (after all, that was a very kind gesture for her to make to begin with), maybe she won't feel guilty (if that is what it is) and come back around.
There has been too much "crap" going around on YT regarding money...I won't even begin.............

(aurgh)
Anyway, things will brighten up........and your friend will come back around.
