Anxiety issue or something else
Whenever I feel stress , even day to day life stress causes chest tightness and heavy breathing. I feel numbness in my legs and hands. Sometimes my legs start shaking and my hand also shivers and automatically my fist closes or tries to hold something and close fist tightly. I sleep a alot . Even then after some hours I feel sleepy. After my breakfast either my head feels heavy or light and my eyes starts closing and I feel so sleepy that I can't resist it for too long and then I sleep again .
