Jessica is a normal girl who enjoys spending time with her boyfriend and shopping with friends, but at any moment her life can be taken over by one of her four 'alters'.
As well as being herself, Jessica can also become American actor Jake, bisexual Jamie, gay anorexic Eddie or 10-year-old cartoon-loving Oliver.
She told Phillip and Holly that she has been dealing with the condition from a very young age and can't imagine living any other way.
"I grew up thinking that I used to play with a little boy named Jake, without realising really that that little boy was in my head," she explained.
"I assumed that everyone had people living in their head, as strange as that sounds, and I honestly didn't realise that I was any different from anybody else."
Jessica was diagnosed with DID at the age of thirteen and says she has learned to manage her condition.
But at any moment any of her alters could surface and it would not be uncommon for Jessica to not reappear for weeks at a time.
She also explained that all five personalities could communicate with each other and she admitted that sometimes it can become a bit too much.
She said: "It can be quite noisy from time to time, as I suppose it would be with about five people living in one brain.
"But it is certainly really eventful."
"It changes on a day to day basis, some days are really quiet, and other days are really noisy."
Joining Jessica in the This Morning studio was her boyfriend Gareth who said he has learned to interact with each individual personality.
"(When Jessica told me) I just took it on the chin...I just said "Oh, that's pretty cool".
"I then got to meet them all and got to learn all about them which was really lovely actually."
Despite the unusual circumstances Jessica lives with on a daily basis, she has continued with her studies and is now studying for a post-graduate degree.
