MHA provided various services including counselling, services in schools and community projects.
Announcing the closure the charity said: “Despite the team’s tireless efforts to meet rising demand, our current income can no longer sustain the level of service we aim to provide.
“Like many third sector organisations across the country, we are facing the stark reality of being asked to do more with less – a position that is no longer viable.”
MHA also called on “funders, partners, decision-makers, and government policy makers” to recognise the need for more investment in mental health services.
It added: “It is vital that charities, like ours, are given the tools and resources to continue delivering essential services to those who need them most, before it’s too late.”
