The actress, who plays barmaid Sunita Alahan in the soap, quit the social networking site in June after receiving "violent, vitriolic" racist abuse.
She explained to the Daily Star: "People even judge me for saying what the tweets said. It feels like people now criticise you for anything and everything.
"But I've taken control so if they feel they've won then that's fine."
Gulati decided to permanently close her profile after receiving offensive messages from users as well as mutilated pictures with captions.
"I don't want it on my computer screen," she said. "Right now I just want to concentrate on my job and getting myself feeling better."
The actress explained that she has yet to go to the police as she does not know if they will be able to catch the perpetrators.
"It's really difficult to track people down and the police know that. But the fact is it was pretty hideous stuff.
"Getting that kind of abuse is not easy... It was really personal. I'm a woman on my own. I don't want to read that stuff. It makes you feel insecure and frightened."
However, she admitted: "I miss the banter and keeping up to date. It gave me access to people I'd never normally have access to [but] I think I had an ill-placed faith in human nature."
The star, who recently won 'Rear of the Year' alongside John Barrowman, added: "It's disgusting and I'm glad I've said I don't want to read it. You can have an opinion - if you don't like the look of me that's fine, but there's a way of saying it."
