She definitely feels like an mystical beautiful Angel born as human for a task or to play a while as requested to God. She must have felt played enough but she must be really happy she found you in shortest of the time she was here. Light a candle for her when you can.. I am sure she is one of you guardian angel now. Be happy. Be happy not be sad. Definitely she was not of normal realm. She was an Angel. 😇 .. Heather is a beautiful name fits her to core.
