Shaking and weak?

Hey Ya’ll! I’m not sure what’s going on, it may not be a big deal, but I just wanted to get a second opinion. I’m in a cold sweat, I can’t stand up without falling because I’m so weak and shaky, and I’m quite dizzy. My heart rate is also through the roof. I do have problems with low blood sugar, but Im not too informed about it and I’m not sure what’s going on….any advice?
