Thanks for your question. My name is ***** ***** I'd like to help you out.
Considering that you are in good health, it is very likely that you are experiencing panic
attacks. These occur when people are experiencing particularly high moments of anxiety
, which may explain why this only happens to you at school and now university. From what you've described, it sounds like you've ruled out this being related to your diet, which makes it even more likely that it is anxiety related.
There is certainly help for this and it is a reason a lot of people go to counselling. Often times at university there are free counseling services, and that may be the best place to start. Panic attacks can be extremely frightening, but if you are able to gain more control of your anxiety in general, these will stop happening. A counsellor should be able to help you work on getting all of this under control. If your university does not provide counselling services, it would be best to see a psychologist or therapist on your own, and they will be able to help you out.
Often times people feel like they have their anxiety under control, but then it comes out in ways like you described. Most likely with a little bit of work you will be able to over come this and be free of these panic attacks. I definitely wish you the best with all of this, and if there's anything else I can do to help just let me know.
