So here Mavis was holding her tears in so she could meet the Faries, but in the present she tends to cry quite easily... Does that mean that she already met the Faries, or that she has given up on her dream?

If it is the latter, I hope she was able to replace the void left by her old dream with a new one, maybe Fairy Tail itself. That would explain why FT is so important to her that she would keep watch over them even after death.
