Ellis, who studied Arts and History at Goldsmiths, University of London, hopes to raise funds for a double mastectomy and chest reconstructive surgery after identifying themselves as non-binary, or genderqueer.
They are seeking treatment privately, after being left desperate by a current 13-month wait for treatment on the NHS.
Ellis told The Huffington Post UK: "I love the NHS but they are pushed for resources. Going private is a big decision, but I want to move on from this part of my life."
The 26-year-old continued: "Since I hit puberty I’ve been saying the same thing. For ten years I’ve been called mad. For two years I’ve been called a sissy little queer.
"This year I want to look at myself in the mirror and relate to what I see."
Ellis' GoFundMe page has receive donations totaling over £2,200 - roughly a third of the total £6,000 cost.
Ellis said: "It means so much to see people contribute. Most people I know are working class and it’s a bit overwhelming. It’s been shared a lot of times.
"I know that even just £5 can be a lot for people."
The Arts and History graduate will go onto study a Masters at Goldsmiths later this year.
"For someone like me, a 13-month wait comes after a long process of coming to terms with their situation and it really impacts our health," they said.
"Being white and somewhat educated puts me in a position of privilege over other trans people, specifically people of colour and/or women.
"I wouldn't be this close to getting this treatment if it wasn't for that."
Kelsea Little, spokesperson for GoFundMe.com, said: “We are very inspired by Ellis’s bravery in sharing this story. The GoFundMe team all send their best wishes and hope the donations continue to come through to help towards the costs of surgery.”
