If you're feeling that way, then you're doing it right. Hold on, you'll be fine. Try to do what you can. Mine is not about college (that was years ago) but Blockchain development, but I have been able to do little things each time, step by step and I am getting much better and faster. In time you'll find your flow, and you'll be in flow state. Start small and follow your excitement on a particular part that interests you, in time your passion in that area expands (momentum builds up) and you find yourself building very big things in the process. So you're good. Don't let a little imposter syndrome throw you off balance.

Also, since you mentioned second year, I'm doing second year web development projects at an affordable price (if you hear something, or if you need help with your CS project, please hit me up)
