Hello Claire:)
First of all I would like to say that in my opinion I find nothing wrong with you at all ! I think it is beautiful that you know who you are and that you are introverted like reading and are different than everybody else. To be honest everyone is different but people these days are so worried about what people think of them that they are all being the same but if they all were their authentic selves, then this would change and we would see a lovely world where everyone was unique. So I would suggest that you embrace being different and enjoy the fact that people will see you different. At least when they think of you they will know who you are because you stand out! When it comes to the negative thinking and analyzing what people think of you, DON’T waste your time! I have been in your shoes before and analyzed SO many thoughts in my mind about what the person in front of me thought of me (all of the thoughts were negative obviously ) and eventually this person would end up being my friend and tell me something SO DIFFERENT than what I had thought they thought of me. And in other times the people I thought might actually like me , turn out to not really care for me at all. So dont waste your time trying because more than likely they are not thinking what you think they are thinking , dont forget everyone has their own way of thinking , own life experiences and own ways of deciding so there is a very small chance you think exactly how someone else thinks. You know how someone you just dont like because they remind you of someone you dont like? Yeah that kind of thing, so you cant really guess because everyone thinks differently. Plus , dont take compliments or insults too seriously because in the end of the day you are the one who has to look at herself in the mirror , so technically no one can push you down or put you up unless you let them! When it comes to the negative thinking I’m not exactly sure what kind of thoughts you have? But remember that your mind is a sacred garden that nothing and no one can enter without YOUR permission !
Hope I helped let me know if there is anything else you would like to know:)
