Heavy breath with Numbness. To approach.

Hello doctor, When i get tensed or cry badly then suddenly heavy breath with mouth starts and it last for 5-10 min , it slowly calms down. Durinf heavy breath my hands nerves , legs nerves pulls closer into fist. Even my mouth gets pulled closer. My hand open fingers closes (gets pulled) into fist. Even after breathing stops, my hands, legs and mouth feels like shivering sensation. I have this problem from previously before 8 years but during that time my hands and legs nerves were not pulled only heavy breathing used to be there. But from 1 year i am facing this issue with nerves . It almost feels like fits but it is not . I happens mostly when i am under stress or when i cry badly or if i eat too spicy and gasping with mouth then automatically it starts. Can someone tell me what could be the issue and what exactly this disease name is and how to approach.
