I used to get that way a lot. I didn't have the ability to take medication at the time so I did it without. I practiced being with people. I think a good portion of it is building your self-esteem, once that was in place things got better for me. The other thing is I would associate prior places that it happened to with the shaking, and am still working on overcoming some of that.
I think one of the key ingredients here is, don't let your past reactions dictate your present or future ones. You can learn some new coping techniques, skills, and re-establish self-estteem and confidence. Something maybe you never had before, or something that wasn't a strong suit for you.
I know for me, I didn't have coping skills, or self-confidence and self-esteem. Coupled with quite a few traumas I ended up in a hole. The hole is a long way aways now, but on occassion I still feel a shockwave or two from it...I cope, I face my fears, and still trying to work my way out of the residual stuff. One moment at a time. And, hey, give yourself a pat on the back and a break for one moment...you have gotten this far, you just have (as I call it) an overloaded outlet/faulty wiring at the moment...the sparks (shakes) will come to pass little by little.
