Your situation is not as bad as you think it is. Of course it could have been better, but trust me - it could have been so much worse! Your dissatisfaction and desperation comes from the comparison of your life to some random benchmark - something that you THINK you should be doing now that you don't, or something that you THINK you should have by now that you don't have. Concentrating on the negatives of your current situation would only make the feeling of desperation worse and will result in inaction - and this would be making your situation even worse.
Here's my practical advice (take it as a VERY high-level opinion, since I really don't know who you).
1. Stop feeling sorry for yourself. It's never helpful. Ever. It just leads to a feeling of being a victim of the circumstances and supports your inaction. Take your current situation and call it "My Starting Point". Now start making improvements, no matter how small they may seem (go shave clean and make a good haircut - this is already an improvement).
2. Start small. Don't think of all the things you want to have eventually. You will have them, but the key is to take ACTION now. Today. Start taking steps that would help you improve your situation.
You want a "real" job? Well, too bad - there just isn't one. Don't blame the job market, Nebraska or whatever. You are just not skilled enough, or not persistent enough to find one. So, take a smaller step forward - take a job that you can take. McDonalds does not sound like a real job? Well, it's a job and better than nothing. During that past 6 months that you stayed out of job, you could have SAVED a net amount of around $6K + have an insurance. You could have used the $6K to pay off part of your debt. Stay for a few more months - and you are debt free! The "future debt-free you" would be very thankful to you for that!
This is a great improvement to your "Starting Point". Yes, it's a small step - but it is a step in the right direction. If you don't take this step RIGHT NOW, then 6 months later you will be exactly where you are right now - just much more desperate.
3. Continue small. While at McD's - keep looking for a job. Every. Single. Day. And don't give up. Small persistent efforts add up to big results later.
Now that you are debt free you can build a bit of a safety cash cushion and then move out of your parents' house. Don't rent an apartment - rent a room. I lived in New York City - Upper West Side in Manhattan - and my rent was... $350/month. Yes, it was a room the size of a queen-size bed, but it was my room. And while there I could save more money to pay for my education. I don't know Nebraska RE market, but I'd guess that it's cheaper than NYC.
So, in summary: stop feeling sorry for yourself. Accept the situation you are in and move on. Think about any improvements to your current situation - no matter how small they may be - and do it. Right now. You just woke up in the morning? Great! What can you do TODAY so that by the evening you are in a better situation?
