Is it normal i developed severe anxiety from university studies

I'm a final year student in uni and lately I've been feeling so lost. In the relentless pursuit of my degree spending the last 3 years instead of 4 with my head buried in textbooks I feel like I lost myself somewhere along the way I never go out, everything I do I do it carefully and obsessively in a way it's great because you always have the best outcome but it's exhausting in all it's enterity. I never used to be like this I overanalyse and overthink everything. I'm always on the verge of an emotional breakdown, I get headaches, running stomach and terrible mood swings. I'm a walking anxiety attack. A lot is riding on this degree and i wish I could stop these anxiety attacks before they consume me.
