Hi, higgins and welcome to WriteWords
If yuo need any help navigating the site, feel free to ask.
As for your rejection, most writers recieve form letters so any personalised rejection letter should be taken as encouragement to continue. If your novel is finished, prepare a couple of dozen submissions (covering letter, synopsis and first 3 chapters) and send them out to Agents who specialise n the genre you're writing in. Certainly don't give up at this stage.
