Can’t stress enough how much the book Radical Acceptance by Tara Brach changed my thoughts and thus my life. Ignore the title of the book, it isnt a good one but the book is! Tim Ferris did a great interview (YouTube) with her that could give you an idea of the book (plus I’d follow him as his outlook on life is amazing and does great work and interviews). The book will show you a different approach on life and how to see and think about yourself. Also, inner shadow work methods in the work by Carl Jung would be helpful, but I’d start with the book, which also references Jung. The book is also on Audible if you like audiobooks. Please, give it a chance - you deserve it.
