Thank you Dumebi for the positive feedback.
Welcome to imposter syndrome. We all have it to some extent.
To calm you down. I believe the hardest part is actually to start interviewing for the jobs.
My rule of thumb is to apply if I match 50 - 80 percent of the job description. Then it's just a numbers game. Maybe you'll have to apply a lot before you get your first job, but you'll get it eventually.
And once you get it, it's actually pretty hard to get fired. If you're motivated, push yourself and show up every day chances are you'll do much better than the majority of your coworkers. ;)

Also I have an article in making on How to get your first job ;) Will publish it next weekend.
