CreditNeeded

Throwaway due to the nature of the question. I am in severe need of rebuilding my credit. Its into the very low 500s I have had 3 delinquencies in my name. These were all from when I was younger but, now I am trying to fix this. I tried getting a secured card but was declined. I make about 30k a year. I have no idea where to start. Any tips for somebody struggling to fix past mistakes? The delinquencies are about 3-5 Years old.

Thanks a ton for the reply I will be reading through as much as I can asap.

I wish that were an option sadly zero credit is much better than bad credit. I may not even be able to get a bank account.
