At the very least, you've accomplished getting married and (even though you didn't want to at the time) had a pretty daughter. You started a family.

You also graduated high school and published self stories. How many people can say they've written something that's gotten published? That's a HUGE accomplishment!

You also have the rest of your life to finish your third book. Your future may seem bleak to you right now, but you have 40+ years to finish that book. I'm sure you'll be able to finish it long before then, too. It's just that current circumstances make it difficult for you to see what your future has in store for you. Once the fog clears, things will get better.

Even if you self publish your own trilogy, that's still an accomplishment. I could never publish my own book, let alone write one in the first place. I don't have the finesse required to write a book, so I doubt I could even self publish something unless it was a pile of crap.
