Struggling with Social Anxiety and Hypocrisy

Sometimes I really feel like i just can’t access some parts of my brain when I’m around other people. Even if someone else is in the room i can’t think clearly. Im a completely different person when I’m alone and when I’m alone i don’t live by the same values I do when I’m around someone else. I guess that’s low integrity or hypocrisy. It’s hard for me to open up and any time someone asks me about my feelings i just don’t know what they are. They’re all full of what i think they want me to think no matter how hard i try to just be honest about how i feel!
