I absolutely love it. I went to school to become a DBA and it's everything I hoped it would be, and more. It's a chore setting up any database structure, and I had those same struggles . If you seriously want to try to get into it again, I'd recommend checking out 2 Day DBA - it's kind of a guide that will show you how to set up, log in, and begin experimenting on your own database instance. All you have to do is create a free account on Oracle's website and you can use just about all of their software for free, as long as it's for learning/non-commercial purposes. Guide can be found here: https://docs.oracle.com/database/122/ADMQS/toc.htm
QA can be a great place to start in IT. Your experience will depend on your agency's structure - some QA departments are siloed and literally only deal with the same kind of stuff every day, whereas others will offer you a more diversified work load. It's an excellent job if you want to go down the Analyst path more so than the programming/hardware ones.
One thing about QA, many orgs and eventually most orgs are looking to automate as much as possible and anything that cant be automated they outsource.
