Social Anxiety.

Hi Fellows...I want to share the problem that i v been goin thru for past 5 years and instead of getting better it feels like getting worse everyday....I m at the point now where i think that i am capable of doing all the things that other do but far better than them....but there is always a feeling that keeps me from doing ....i feel like everyone is watching me and they ll laugh at me for my actions....i am a university student and it feels a great pressure to go there daily....i m just tired now of all this shit....i cant talk to others properly....always anxious ...racing heart...sweating ....shaking .....these are supposed to be some good days of life but for me these are just worse.....Everyone around me is always so calm and do presentations and anything asked but for me it is a great pressure and sometimes i have to leave the class without asking my professors ......i hope that someone will understand and guide me to a better living coz i m just sick of this kind of life.
