Plans to â€œtransformâ€ attitudes to mental health, with a focus on children and young people, have been announced by Theresa May.
Additional training for teachers, an extra Â£15m for community care, and improved support in the workplace were among measures announced by the PM.
Mental health experts said more funding was needed to improve services.
Mrs Mayâ€s speech comes as she outlined her plans to use the stateÂ to create a â€œshared societyâ€.
The government says, at any time, one in four people has a mental disorder, with an annual cost of Â£105bn.
The prime minister said mental health had been â€œdangerously disregardedâ€ as secondary to physical health and changing that would go â€œright to the heart of our humanityâ€.
Health Secretary Jeremy Hunt told the BBC care for children and young people was a â€œblack spotâ€ that needed urgent attention as the pressures of social media, cyber bullying and a big increase in self-harming was a â€œmassive worry for parentsâ€.
Mental health charity Mind said it was â€œimportant to see the prime minister talking about mental healthâ€ but the proof would be in the difference it made to patientsâ€ day-to-day experiences while Sane said the plans needed to â€œbe matched by substantially increased funds to mental health trustsâ€.
Dr Sangeeta Mahajan, whose 20-year-old son Sargaar killed himself after being diagnosed with bipolar disorder, said better access to services was essential.
â€œThey donâ€t discharge patients with adequate information,â€ she said. â€œThe doors were closed to us.
â€œWe were told you either go to A&E or your GP and that is the only way you can come back to us.
â€œWe had no direct access back to the specialist services. That is wrong.â€
Bed shortages have meant some patients have had to travel hundreds of miles for treatment.
Fiona Hollings, 19, was treated in a specialist eating disorder unit for her anorexia in Glasgow â€“Â nearly 400 miles away from her family home in High Wycombe, Buckinghamshire.
Mental health campaigners certainly recognise the significance of the latest initiative headed by the prime minister.
Theresa Mayâ€s focus on mental illness in her first major speech on health will in itself raise the profile of the issue and reaffirm the drive to achieve true â€œparity of esteemâ€ with physical health.
Promoting mental health first aid training in schools in England illustrates the prime ministerâ€s desire to see this as more than an NHS-only issue.
But there is no new Treasury money for the plans. Funding for care is still challenging. NHS Providers, representing mental health and other trusts, predicts the share of local NHS budgets devoted to mental health will fall next year.
Ministers will argue money isnâ€t everything but it remains an unresolved part of the mental health agenda.
Professor Sir Simon Wessely, president of the Royal College of Psychiatrists, welcomed Mrs Mayâ€s â€œnew and bold visionâ€, but added: â€œWe have a long way to go before mental health services are on an equal footing with those for physical disorders.â€
Businesses also welcomed the workplace initiatives.
Simon Walker, director general at the Institute of Directors, said employers had â€œa real role to playâ€ in ensuring the mental health of their workforce.
But while education leaders backed the ideasÂ that focused on young people, they also had concerns.
Malcolm Trobe of the Association of School and College Leaders, said the major problem schools faced was a lack of access to local specialist NHS care and said government plans had to be â€œbacked up with the fundingâ€.
Russell Hobby, of school leadersâ€ union NAHT, agreed: â€œRising demand, growing complexity and tight budgets are getting in the way of helping the children who need it most.â€
Liberal Democrat Norman Lamb, a former health minister, said Mrs May was announcing policies already agreed under the coalition government and called it â€œa puny responseâ€ to â€œcover up for this governmentâ€s failureâ€ on delivering, while Barbara Keeley, Labourâ€s shadow minister for mental health, questioned why funding was not being ring fenced.
Mr Hunt said the government had endured a â€œslightly patchy startâ€ with funding, but that with about Â£1bn more being spent on mental health than two years ago things were â€œgoing in the right directionâ€.
In her speech the prime minister also described her wish to create a â€œshared societyâ€, with the state taking a greater role in ending â€œunfairnessâ€.
The emphasis on a â€œshared societyâ€ marks a contrast with her predecessor David Cameronâ€s â€œBig Societyâ€ agenda, which relied on voluntary organisations rather than state intervention.
