I vary from Vinayaka on this one. Actually this is very bad that you let Tulsi Devi dry out, and then dropped Her pot and it broke.
Pray before Her if She is still with juice and spunky. Yes, it is time you care for Her a lot, and then you should give Devi to another with full truth on the story.
Pray to Lord Vishnu at this juncture. I am not saying it is "bad luck" - it is actually like running over a baby kitten or something horrible like that.
You will have it on your Akashic record. You should and must feel sad. To become happy again, perform some sort of penance.
I would perhaps recommend you chant a prayer mantra to Tulsi 108 beads for 16 rounds for the entire day of Sunday and crying tears before this picture:
