The 30-year-old actress, who plays Rachel Breckle in the ITV soap, had been dating fellow actor Andy for five months.
According to reports, Andy ended their romance after struggling to deal with their relationship in the limelight.
Gemma has received tons of support from fans online, and she told one fan on Twitter: "I have amazing friends and family and a very strong liver... Thank god after the last two weeks."
Keeping in good spirits, Gemma said to another fan: "It's OK. I'm strong. Heartbreak can always be turned around. You know me. Vino, jazz hands and a mingle."
Gemma and Andy met in a chance encounter while on a train, with Andy trying his luck by telling Gemma that he had guest starred in Emmerdale - not realising she was on the soap.
Gemma spoke to Reveal in February about her romance, saying at the time: "We've only been together for three months and it's still early days but I'm really happy, he's a star."
