Not Being Invited to Work Events

I am pretty bummed about the fact that yesterday my coworkers were talking about going to do an event. They were talking about the plan and said that we will meet up and go. So I came into the office this morning thinking someone might pick me up and my boss came through and said “hey what’s up” to me grabbed a red bull and left. I looked out the window and he was gone. Supposedly our president, a couple PMs, him, and a couple estimators went(they wanted to bring him to an event because this would be his first big event here). Even though im still 10 months in. I haven’t been to something like this before. So I came to conclusion that I was literally left out. It hurt because i am still pretty new here and the other guy who is our estimator started a couple months after I did. My boss yesterday literally pointed at me and said I will stop by and pick him up and our other project manager. Am I overthinking this? Just feel like after times like these in the past, I don’t fit in with the company or the people if they tend to leave me out.
