I have been struggling with this issue for a really really long time now. Whenever I find myself in a new place, or a new crowd, I have this habit of hiding myself. I just want to hide, go home and sleep. Even in the most important meetings, gatherings, I always come up with excuses to not go because I get flustered, too anxious, too bothered in the presence of others. Whenever someone asks me something, even if I have a proper knowledge and information about that thing, I become so stuck, frozen on the spot and it makes such a bad impression before others. I hate it.
I'm almost 28 now, and this thing has been ongoing for so long. I hardly survived college. I hardly survived the only workplace I was ever in. It is too much for me to be around people in general. I don't have any kind of social battery. I don't even show up for my own self. I have let go of many opportunities, friendships because of my this habit. I am way too under confident about myself and it shows up in every aspect of my life. I really want to work on it and get over it already but I just can't seem to! There was a very important exam the other day, that was super important for my career but I couldn't show up. I keep thinking about things and I give up. What issue is this?
