How can I get a GED?

So I "graduated" this year, and my diploma is technically official and accredited. In Pennsylvania where I live, you need to have an evaluation every year if you're homeschooled, and during the evaluation in your last year of highschool, as long as the evaluator believes you meet the requirements, you get an accredited diploma. I got a diploma that way, but my mom faked all the records like the GPA, transcripts, course list, and attendance logs to get it for me, and I know I definitely wouldn't have met the requirements to graduate otherwise. I didn't know it at the time but apparently that's fraud, and it also just really doesn't feel right to use it and I know for a fact I didn't earn it, and I wanna use it as little as possible.

So my question is, how do I get a GED or another highschool equivalency? It's in the rules that you can't get a highschool equivalency if you already have a diploma. I don't know about trying to get it voided since I still live with my mom and I don't wanna risk her getting in trouble if I try to get rid of it, since I kinda need a place to live. What should I do in this situation?

Sorry if this isn't written the best or formatted the best too
