Wille, it's going to be hard for anonymous people on an internet forum to give you relevant advice. What do you have for support: parents, career counselor, academic advisor, mentors?

Anxiety and panic attacks mean you are in fight-or-flight mode, so it makes sense that you are considering "flight." But as someone who has frequently chosen flight in the past, at some point you need to fight. Or get our of fight-or-flight mode, which you may not be able to do on your own. 

I know many people, including myself, with a similar dilemma who ended up in the construction field. There are some very well educated carpenters who enjoy the creativity and pride of building, and like moving around all day instead of sitting at a desk dealing with office politics. You have to deal with other things, including weather, heights, tools that can cut your parts off, but it could be something to consider. I did it for ten years after college before focusing on design, and miss aspects of it every day. (Waking up to -5°F this morning makes me appreciate my cozy office job, though.) 

If you are focused on a white-collar career, you'll need to think about and understand your talents and motivations, then learn the skills you need to be successful.
