Thought to discard

I’m doing the podcast #185 study guide and want to say goodbye to the long held thought that I don’t fit in. Not in a way that people think I’m weird or unwelcome, but that they are neutral to my presence. What I want is to feel like I belong in my groups and community (as much as I view others as belonging). I tend to question if anyone would care if I was there or not. I know I need to accept myself first and I can also shut the thought down by telling myself I don’t think that thought anymore. Any other ideas for how I can create the feeling of belonging or thoughts I could be using?
