I came across this call-out for poems in Writing Magazine, by a blogger called Tracey Ward, who wants to raise the profile of mental health issues and sufferers. (I am not sure what will be done with any proceeds from the book, should it make a profit.) Tracey is currently seeking crowdfunding, in the hopes of publishing the anthology in hardback. More information here.
The deadline of 12 March 2018 is fast approaching for this mental health anthology from indie press Bad Betty. Contributors will be paid. Full info here.
