Good for you! My advice would be to hang in there and keep at it. I'm a fairly new runner also and you will have set backs and frustrations but keep plugging along and it will all pay off. I didn't progress as fast running as I did on the bike---it was a lot slower process---but I've been at it for almost a year now and it's paying off.
