It could be anything from just having excess energy that you need to burn off, to adhd to ptsd to a nutritional or diet deficiency. The only people who can diagnose you are doctors, and no one on this form can properly help you other than just toss ideas at you. I've heard paxil is really good for anxiety. But this might be more than anxiety because you have a resting tremor. So it really could be anything. Your doctors should do a total body scan and make sure all your blood work is normal, like check for blood sugars, allergies especially with food, and they should rule out other things. Make a list of symptoms and talk to your doctor about it. Tell them about your tremors, excess energy, high alert state, trouble staying asleep. I'm curious about your caffeine intake. Maybe cut down on coffee because some people can be allergic to certain things and it makes their body go out of wack, doesn't always present the typical symptoms one would associate with allergens. Spend that energy every day doing something like going to the gym, eat healthy, make sure you stay hydrated and drink lots of water because shaking is often associated with dehydration. Manage your stress or your startle response by making it your first priority to stay calm and relaxed and put your own feelings before everything else that stresses you out. Your emotions, or mental well being, is just as important as your physical well being. If you are smoking, stop, or if you are drinking alcohol, stop. These two things have also been known to cause shakiness or tremors and they're just not good for the body anyway. Make sure any medication that you might be currently taking is looked at by your doctor to address if whether or not that could be causing your tremors or on edge feeling.
