I’ve worked really hard getting a certification and landed an excellent part time job. I’m in college and my grades are the best they’ve ever been despite my increased workload but I can’t stop constantly thinking about the past. There isn’t a moment in time where I don’t feel anxious, as if I don’t deserve this relative success I’m having. I feel like a fraud. I don’t know if I’m making any sense.
What you’ve got is a maladaptive cognitive structure you’ve set up for yourself, and the only way out is to learn a new way to think about/relate to the past. Practicing mindfulness can help you learn to recognize when a thought isn’t serving you and be able to let it go. CBT and Acceptance and Commitment Therapy are also good options for what you’re describing
