That's really scary. Since your dad's a doctor, did you ask him about any kind of anxiety medications that you can take? High blood pressure is really dangerous. We also have a device for measuring bp. It's pretty useful. I can totally relate to the skipping presentations thing, anxiety shoots through the roof. One think that helps is practicing the presentation over and over again, getting the subject matter by heart. I usually do some breathing exercises to calm my nerves before attending interviews. Honestly, this is one of things that held me back from going for an economics degree. Don't think I can handle that much interaction yet. Kudos to you for doing what you want. Just make sure you get that anxiety under control.
