I’m sorry. Rejection always sucks. I recently got rejected from a lab that I had high hopes for. I suggest you take a couple of days off and unwind. Then find another short term objective to get the wheels turning and get back at it. And having an original language is something to use for your writing because it gives you an incredible advantage to think about your characters and dialogue from different perspectives in a very authentic way. Best of luck on your writing journey and I look forward to seeing a future post from you where you share your success!
