An MP with bipolar disorder said care she received had been "patronising, reductive, inconsistent and non-existent".
Jen Craft, the Labour MP for Thurrock in Essex, created her own treatment plan due to her concerns about existing mental health support.
She called for an urgent overhaul of community mental health care during a debate in the House of Commons.
"I made the decision that I deserved to live and I deserved to live well – and also that my children deserved their mum," Craft said.
MPs were discussing an amendment to the Mental Health Act, which aimed to reduce the use of detention and give people more rights over their care.
Craft was diagnosed with obsessive compulsive disorder (OCD) as well as bipolar disorder by her 20s, but said she only received "good" care in exceptional circumstances.
"I have never been asked what it is that I want from treatment, what it is that I want for my life and how I can be helped to get there," she told Parliament.
"I have received care that is patronising, reductive, inconsistent and non-existent."
