Personality Awareness or Overthinking?

I’ve started to question some of my behaviors and whether or not they are toxic. I don’t know if this is just insecurities and I’m overthinking, or if I am just over sharing my opinion, being a know-it-all, or just talking too much. I really enjoy social interactions most of the time, and part of that is I liking to talk about opinions, facts, and stories. I catch myself in what seems to be over-sharing when I feel like I’ve been talking too much or repeating myself, and then get restless when other people talk for as long or longer than I do. My attention span weakens the further someone talks before I can say anything. I do care about what they have to say, but I can feel when I’m losing someone, and I feel like I’m wasting their time. I guess this could just be undiagnosed ADD or ADHD. I just am always thinking or analyzing something, and when I get the chance, I really want to tell someone and have a conversation about it. I also just like to be very open with my friends and let them know what I’m thinking, how I’m thinking, and how I perceive things.
