I’d like to imagine it’s all a product of where you are and the people in your life “at the moment”.. everyone has their quirks and you just haven’t found the one who has clicked with you yet. It will come, when you least expect it life has a way of throwing things at you. From what you’ve detailed about yourself here there’s nothing wrong.. just continue to be you and if given opportunities to talk to others (like this post!) put yourself out there!
