Is that because you're already in therapy? If so, skip the following; if not why not seek out a good therapist who can guide you in CBT, or something similar. What you're describing is common, therapists have super good tools and strategies to help you with it. Therapy is no big deal; no different from having a personal trainer at the gym!

On the point of feeling like an imposter, or feeling afraid of looking stupid: there are a handful of people who I think of who are super smart and accomplished, and yet humble and gracious, and not afraid admit to not knowing something, etc.; trying to keep them in mind and emulate them has I think helped me with some of the issues you mention.

Take care. I'm sure you'll be able to find some strategies that work for you.
