How to overcome social anxiety?

I have this anxiety. Please can anyone help me? I don't know when these wave of thoughts hits me. I am a science student and everytime I do my practicals my hands begin to quiver. As if I don't have control. I am not able to talk and go out when there are a lot of people. I feel low for no reason some days. But some days I am fine. I just wanna be extrovert. I don't wanna overthink about every single thing.
