Hello, I'm having so many troubles recently. Basicially I have a University situation-problem going on for a long time now and I'm extremely stressed about it. I study abroad, so it makes it worse. And now ım having these symptoms incluing, headaches (not severe), nausea, fatigue,anxiety, having hard time breathing (its like something just stuck in my throat) and whenever I go outside, just by walking, my heart goes super crazy. I mean ı can feel it beating so hard and fast. so my question is, is this because of stress? or should I be concerned about it and go back to my country to check it up
