I just had the anxiety symptom weeks ago. I am an international student which has just arrives in the states for 5 weeks. The first week I was here i feel so homesick and sad and I can't barely sleep due to the jetlag. The 2nd, 3rd and 4th week was fine for me and I thought I started to adapt to the environment. However, last monday i started to feel anxious and it stays until today which is already 6th day. My heart beat so fast, i can't stay still and have the urge to move, walk or run and i feel tighten in the chest. when i try to stay still I will feel suffocating and the feeling is there until I fall asleep at night. I know the feeling appear due to overthinking and loneliness but I don't know how to control my thoughts. Everyday is hell for me. I feel time pass by so slowly and I feel exhausted. I tried the breathing techniques but it doesn't work and ended up I need to take a walk to feel better. I walk 8 miles per day. I was thinking to take prescription to overcome the problem because the anxiety is affecting my studies. Anyone here have advice what should i do.?
