Is there anything wrong with being an introvert?
Seriously, this is not a problem, unless it makes you unhappy. I am an introvert in that I get more peace/energy in being alone generally than in social situations and I have difficulty keeping up friendships too, partly because I can’t be bothered to invest a lot of time in most of the friendships I have since I would rather have solitude and partly because, unless I really feel connected to the other person… I get bored occassionally. You don’t need to change, if this is who you are and what you wanna be, they should accept you and you should accept yourself. Good luck girl.
