Hey, I'm kinda new to this so bear with me.

I'm sure this comes up relatively frequently, but is there any way to access your wallet outside of the site you signed up for it on? I mean, I know there has to be, but I've gotten myself into a super situation.

Back in 2013 I started a wallet on Blockchain and then didn't touch it for a few years. I've moved since then and my computer hard drive had a pretty serious failure. I tried to get back into my account after digging through some emails, I think I tried to reset my password too quickly so now I have an account that I can't seem to get the password to, I "disabled two factor verification" because I wasn't really sure what I was doing there, and I have no idea what the verification words are.
TL;DR, I made a series of stupid account decisions.

I do have a wallet backup .json file and I know my wallet ID, but I think that's about all I do have.

Did I completely mess this up? Can I access my wallet again through a method that is not the original website?
