Limiting belief

Hi coach. Through the work I’m doing in scholars I have discovered that I have a limiting core belief that I’m not good enough/ I’m not worthy. I’m finding that most of my thoughts I have are filtered through this belief and it’s a really painful way to live. I was severely made fun of when I was younger and I think that’s where all of these shameful thoughts come from- it’s like a memorized habit that I can’t shake. How do I go about changing this deep seeded belief that I really don’t want to believe anymore?
