More than 1,100 people in Guinea survived the deadly virus - around a third of whom are estimated to suffer from depression, and four in 10 from post-traumatic stress disorder, according to The Alliance for International Medical Action (ALIMA).
Most suffer physical problems, including joint pain, headaches and chronic fatigue, health experts say.
Yet many survivors cannot afford health care, said Ivonne Loua, a doctor who runs ALIMA's survivor care programme in Guinea.
"It is important that survivors and their families have access to quality care, because many are unable to work and cannot afford to pay their own care," she said in a statement.
The Ebola epidemic killed more than 11,300 people and infected some 28,600 between 2013 and 2016 as it swept through the West African nations of Guinea, Sierra Leone and Liberia.
While the outbreak came under control last year, many survivors have been shunned by their families, communities, and even medical workers.
The virus can lie dormant and hide in parts of the body such as the eyes and testicles long after leaving the bloodstream - raising questions about whether it can ever be beaten, with West Africa's 17,000 survivors acting as a potential human reservoir.
While experts say the risk of Ebola being transmitted from survivors to others is low, suspicion lingers.
Almost half of the survivors that ALIMA has provided care to in Guinea's southeastern town of N'Zerekore, said they still experienced stigma, which could worsen psychological problems.
"They are traumatised by what they experienced and overcame," said Davin Mpaka, a neuropsychiatrist with ALIMA.
"Many feel like they have nothing else to gain from life, but they have no one to talk to about it," he added.
Authorities in neighbouring Liberia said this month they were investigating the death from childbirth of a woman named Time magazine "Person of the Year" in 2014 for her work fighting Ebola after reports that health staff were afraid to treat her.
The death of Salome Karwah, whose sister said medics refused to touch her because she contracted the virus in 2014 - has raised fears that stigma surrounding Ebola could lead to preventable deaths of survivors.
