Whilst it is always going to help no question about it, Mental health isn't and doesn't have a one size fits all remedy. Having had 2 members of family commit suicide, one just at the beginning of last summer, 20 years after the love of her life died of cancer at 36 years old and couldn't get over it and the other in 1999 it is without a question something that shouldn't all be lumped in one category. Not to lower the tone, but mental health care in this country is an after thought compared to other illnesses. But for me personally, exercise changed my life in more ways than one.
