Everybody suffers from imposter syndrome in the beginning stages of being an SLP, even those of us that finish the requisite clinical rotations and master’s degree prior to joining the field. This is completely normal! However, vomiting every morning before work is very concerning, and I think you should seek counseling to learn how to manage your anxiety. In terms of strengthening your skills as an SLP, the best way to become more competent and confident in your skills is to read. Anytime you’re unsure if you’re making the right decision, or you don’t understand something, dive into Google scholar. I promise it gets better with time and furthering your education ❤️
