Help for a returning student

Hello I live in california and currently hold a LVN license by challenging the board. I have been working at a SNF for about a year and a couple months. I unfortunately did not pass my RN classes twice so I cannot go back to the original college. I also do not have an official degree from the college. My college credits may have expired from my community college. So long story short all I really have is an LVN license. I really want to continue my career as a RN. I was wondering if anyone has gone through a similar situation. I would really like to get some information please. Im very lost and don't know where to start. Any information would be great. thank you so much.
