Figures show growth in the numbers of people seeking help, prescriptions and waiting times
in 2017/18.
On average, they waited 60 days for a second appointment, longer than the national average of 53 days.
Adults in Cheshire are also increasingly seeking help for mental health issues.
Fit notes for mental and behavioural disorders, including stress, which are issued by GPs when someone has been off sick for more than seven days, are on the rise.
In the year ending in July 2019, doctors handed out 31,145 fit notes.
That was also up from 28,053 in the year to July 2018.
Separate figures show that GPs prescribed 1.4 million antidepressants in the year to August this year - an increase from 1.3 million in the same period in 2018.
As well as treating increasing levels of mental health issues, those working in the NHS are also being increasingly affected by stress.
Between December 2017 and
November 2018, doctors in this area lost 2,275 days due to stress, up from 2,273 days in 2017.
Other figures show in the year to November 2018, full-time equivalent NHS workers lost 99,530 days to stress.
A spokesperson for the charity Mental Health Foundation said: “Millions of us around the UK are experiencing high levels of stress and it is damaging our health.
“Stress is one of the great public health challenges of our time, but it still isn’t being taken as seriously as physical health concerns.
“Stress is a significant factor in mental health problems including anxiety and depression.
“It is also linked to physical health problems like heart disease, problems with our immune system, insomnia and digestive problems.
“Individually we need to understand what is causing us personal stress and learn what steps we can take to reduce it for ourselves and those around us.
“We also need to change at a societal level.
“This includes ensuring that employers treat stress and mental health problems as seriously as physical safety.
“We are also asking for wellbeing days to be provided to public sector workers as part of reducing the pressure on those who work hardest to look after us.”
The Mental Health Foundation has suggestions for how to reduce stress levels.
It said there is a growing amount of evidence showing how food affects our mood.
They also suggest reducing or stopping smoking and drinking alcohol.
Doing physical exercise can also be very effective in relieving stress, even just going out and getting some fresh air.
Experts also advise taking time to relax and be mindful.
Mindfulness involves paying attention to our thoughts and feelings in a way that increases our ability to manage difficult situations and make wise choices.
