EXCLUSIVEGia Allemand turned to the church just one day before her suicide ... paying close attention to the service and even taking notes during the pastor's sermon, TMZ has learned.
Sources close to the former "Bachelor" star tell TMZ ... Gia was a practicing Christian and attended a Sunday service at her local New Orleans church on August 11.
One source close to Gia tells us the reality had been struggling recently ... "She was a Christian, but couldn't be fulfilled. She thought the world expected more from her. She put so much pressure on herself and couldn't see the love around her."
We're told Gia had been venting about her relationship with NBA player Ryan Anderson in the weeks before her death, but Gia's concerns were pretty ordinary for a couple that had been dating for more than 2 years.
Hours before she attempted to take her own life, we're told Gia went about her daily routine as if nothing was wrong ... even teaching a 1:30 pm class at an exercise studio on August 12.
Later that night, Gia's boyfriend discovered the reality star in her home after she had hanged herself. She passed away two days later.
