Social anxiety

Anyone else feel existential dread whenever talking to people? For the past couple years it’s gotten very hard to put myself out there. I just feel like an outcast everywhere I go. I never feel safe around anyone anymore. My thoughts are either filled with anxiety or rage, even though I keep them to myself and act calm, cool, and collected. It’s exhausting to constantly be scanning myself for everything I do and making sure I look the part for wherever I am. It’s gotten worse everyday and now I’m isolating myself. I crave connection so badly but whenever I’m in a social situation I freeze. And then I’m filled with a soul level of shame. If anyone’s felt this way before, has anything helped you?
