/lit/ - Literature

Hello, /lit/.

I don't come here very often, but I thought you may have some suggestions. I was recommended by my psychologist to write things down, but I can't write in a journal format, the words just kind of die, though I have found that I am more comfortable writing things down in poetry. However I don't think I am capable at the moment to write anything I'm happy with. So my question is: how do I learn to write poetry to a passable standard? Are there any books that teach the basics of not being shit?

I don't expect to read a book and suddenly be a poet, obviously, but something that could teach me about the technicalities of things.
