I get really nervous in social situations and do not know what to do..its to the point where i cant barely speak because im so shaky and people can hear my beating heart. I have servere difficulty in making anykind of eye contact...i feel like i see too much when i look into people's eyes, what they are really thinking.When I try to speak my voice just get compressed and my sound listen like whistling 

I do have no idea what to do

Is it really serious problem or do I have see doctor ?

Good suggestion needed.. seriously..
