My nerves are very weak from childhood. I am not as strong as others. Have not participated in any games at school neither activities. Still feeling hard to get up in morning. Even somebody shouts I feel shaking body. I am 30 years of age male. Want to find a way to be stronger. I started doing workout regularly. Feeling bit good but can not improve my exercise time as well. Please guide me, if came across such cases like this before. I feel pain sometime from my shoulder till palms with shaky hands while sleeping at night too.
