Overstimulated or Over having Birthday Parties?

Today was my 28th Birthday Party and I am going, to be honest with you, I did not enjoy a second of it because it very quickly became overstimulating and not very fun for me. I would try and try to calm myself down inside the house people were constantly coming in and out of the house which made things more stressful because they would bombard me with questions or want to have conversations that I could barely focus on because I just wanted freedom and space to breathe. So why did I pose the question? Because I want to know if I was truly overstimulated or just over birthday parties and was wishing for freedom from everyone.
