Hang in there, and just ignore all those people (and there are loads) who tell you that "you are never going to make a living from writing", "no one is buying 'X genre' books these days", "there's a glut in 'X genre' market" - do you want to hear more. The only guarantee is that if you don't write, and don't give it a go, then you will get exactly nothing.
I don't know if the nay sayers are just wowsers generally, or if they are jealous because you are trying something new and creative. Life is to short! Write because you love it.
