I have a friend of about 1 year. We started out well and seemed to be comfortable with telling me anything. We hang out a lot, at her house, lunch, gm. I thought i did know about her but i did not. She's very secretive. the issue is i tried inviting her out to meet my family. (just sisters, cousin.. not the whole big family), she would either come up with an excuse or ignore. So i tried one last time and invited her out to meet my cousin and sister to a restaurant. she replied with a voice message, she sounded sad and was saying she doesnt know if she wants to go, shes nervous, anxious, her heart is beating fast, she doesnt know anyone, theres a lot of people and we ended up fighting because i 'didnt let her explain herself and got mad at her for refusing my invites'.. bla bla. she refused to tell me whats wrong. i googled it and the only thing i could come up with is social anxiety. Can anyone help?
