Yes, consumed by gangrenous tuberculosis, she was racked by violent, bloody coughing fits. Her final Communion was August 19, 1897, 41 days before her death. (Cf. St. Therese of Lisieux: Her Last Conversations, tr. John Clarke, OCD, 295-6)
(Remember also that at that time, daily Communion was not a possibility for anyone.)
A possible Eucharistic miracle about which I only learned recently:
Based on certain statements she made, it is believed that, when receiving Communion often became impossible during her last illness, Therese “asked of the infinite Love of God that the sacred species should not be destroyed in her” and that the Eucharistic Lord should “remain in her as in a tabernacle”. (Cf. Angel de las Gavarres, Therese, the Little Child of God’s Mercy, 228-235)
Wow!
