Host Chris Harrison introduced the 26-year-old assistant district attorney on ABC's After the Final Rose special, which aired after Monday night's Bachelor finale.
"I feel all in," she told Harrison. "I feel mentally all in, emotionally all in, physically all in. I am in a place in my life where I'm just so ready for this. I hate to say it because I don't want to jinx myself ... but I am ready. I've never felt better in my life about this and I'm just excited."
Dorfman became a contender for The Bachelorette when she confronted Galavis about his seeming disinterest in her personality and general sleaziness.
Galavis, who chose Nikki on Monday but didn't propose, is even unpopular with show producers.
"Everyone on the show is just so over him and cannot wait for this season to be over," one insider told E! News before the finale.
Despite her difficulty with Galavis, Dorman still has faith in the show format.
"I felt real feelings ... I think it can happen anywhere – especially on a show like this. I mean why not? Why not?" she said.
