I feel the same way. I hide from people and avoid them. I cut ties from old friends because I felt they would be disappointed in me that I am not good enough for them . I always worry what others think of me or I guess what they will think about me as a lower person not good enough and useless .
A few weeks ago I sat in my mum's house while her neighbor was visiting. The whole time she was complementing my sister about what a great mum she is and how beautiful her eyes are . I just sat there like I didn't exist .
