these days I am experiencing numbness in my toes ,, fast heart beats,, weakness,, my left arm gets so weak that i can barely move it , i get sick and vomit even if I ate nothing. I am 19 years old ,, I am really sad nowadays and i have a really big problem with my mother so I am wondering if these symptoms is out of sadness.... through out my life I've always experienced fast heart beats and few chest pains but the numbness and weakness i have not experienced at all. I will be very grateful if u could diagnose these symptoms for me .Thank you very much :)
