Feeling Low

Currently I am working in TCS with 6 years Experience. Actually I am badly feeling like I have not received any experience from TCS. In the project I was worked as Support role and one of the framework which most of the people don't know. Know I am planning to switch but I feeling like I don't know anything.

Now I am learning Spring boot through external paid course. I have one question when I try to switch are they consider me as fresher, because I don't have hands on experience on spring boot.
