I love both novels, so I sincerely wish you luck! However dropping a couple chapters and disappearing is really not the way to go! In my opinion, consistent releases are a must, even if it is only 1 chapter a day/week/month... That way the readers expectations are not raised to be "betrayed". Once again, good luck!
You shouldn't try too hard, setting goals or writing both novels at the same time. You should only work on your story when you feel like it, even if it takes a long time to complete. After all, you've done an excellent job so far and it would be a great loss if you didn't finish the job after so much dedication. For me, you could post the chapters in your native language and leave the English editing for another time. However, even if you end up giving up, I can only thank you for sharing your stories with us. Thank you very much.
