While you are still in school, just work through all of hackerrank.com .. That will bring you some confidence but you have to do the work. Jobs in tech can be varied. You could be writing code, you could be testing code or you could become an architect or work with customers in some technical capacity or even teaching. The most important part in coding is getting the design. With any design there is no one correct solution necessarily and you have to view software development as iterative, even more so in a collaborative environment. So go easy on yourself. I would recommend you look into cognitive behavioral therapy as well. Pick up a book from the library. Find time for you friends and keep a regular social routine. It could be lunch or coffee, I would avoid alcohol.
