Vulnerability hangover?

I just published my first courses. It is the accumulation of so many years of failure, grit, and sacrifice to create my business and all the intellectual property I’ve created and am just getting started with sharing. When I hit publish, I had this overwhelming feeling of pride and vulnerability and I was really just trying to sit with it and feel all the emotions knowing that these are rare feelings I’ll get to experience. However, it all became over whelming and I just started good crying uncontrollably. I keep thinking to myself that I am good crying and just trying to feel the experience, but I also have this thought that something is wrong because I am crying. My question is, is this normal? Should I be feeling like this? I didn’t have these emotions even when I earned my Doctorate. Nothing feels wrong but it is all just a lot.
