I was trying to write this email

So, the other day I was trying to write this email to my professor, and I thought I was being all clear and professional. But after I sent it, I re-read it and realized I had a bunch of awkward phrases and run-on sentences. Now I’m sitting here cringing because I’m sure it made me sound way less capable than I actually am. I’m just frustrated because I don’t want to come off as sloppy, especially when I know I can do better
