GED would take less time. then work on getting an associates degree at a local community college. some may offer both programs. look around online, see what the requirements are, and speak with counselors.
if you have no criminal or medical issues, maybe consider the military. you get paid training and experience towards a job. and they have hundreds of jobs that aren't combat or infantry related. and plenty of them can translate to the civilian world.
but, without a high school degree, you need at least a GED, AND 15 college level courses, or about one semesters worth.
if you join the service, you get many benefits during and after your service, including the GI Bill. which will help pay for higher education if desired or to advance within a company.
the military isn't for everyone, but it can be for those qualified and looking to get a jump start on a career, travel, help with college, or just wants to serve the country.
