What To Do For Discomfort In Making Decisions?

Hello, I am not sure how to describe my problem accurately but I will give it my best shot. I dont really know who else to ask about this kind of thing...but, I digress. My problem, briefly, is that I believe that my brain may be functioning at a less active (or more efficient) level than the people around me. By observation of said people, I have come to the conclusion that I have far less desire to socialize, bond, or even engage in casual conversation than other people. I become quite unsure of myself and feel like I m not doing the right things right when I actually do have to converse with someone. I feel like they re looking at me like I m from another planet alot of the times. I m not particularly concerned about others opinions of me necessarily, but I find it disconcerting that I cannot engage socially with others with any sense of ease or comfort. Quite the opposite. I ran out of space to list symptoms, please get back to me and i ll try to be more brief going forward!
