My friend, what you need to do is to release all the tension that you have, the restlessness and tension that you feel within.

What is happening right now, is that there is a lot of energy within you, but you don't release it. When you don't express the energy that is in your body, it becomes parasitic. And what is the opposite of expression? It's depression. Not as the mental illness, but literally the act of depressing your energy. Now different people react in different ways. You seem to be naturally a bit more highly charged. Negative emotions that have a high charge, for example: anger, agitation, anxiety, restlessness. That's the case with you. People with a lower charge are more likely to get: apathic, bored, depressed, tired etc...

And instead of letting all this excess energy out, you're holding it in. Mainstream western society doesn't know the answer to your solution too, so they give you meditation to calm you down. But in reality, it's just an supression of the sypmtoms. It doesn't get to the core, to the root of your problem. Most of the medication either doesn't work properly, or just replaces old bad symptoms with new ones, these we call 'side-effects'.

The answer is not complicated at all. It's actually very simple. Let it out! You already said that you felt like you wanted to 'pace around'. That's actually not a bad start, it is already better than holding your energy in. But an even better option is to release all of that energy you have! Go jogging, shake you body loose. Really shake your body! Make sounds with it if that feels good to you! Scream if you feel like screaming, yell if you want to yell! You need to LET IT OUT! Don't hold back your energy, or it will become parasitic.

It's either expressing, or calming your energy down. Another thing you might try, is to calm yourself by doing deep breathing exercises. Calming exercises won't release the agitation (because it's not a release exercise), but it can make it less agitated and you will feel more calm and peaceful. You can try both, just feel which one of these two different types of exercises is more applicable to you at that moment. Different types of emotions require different types of methods to work on. Perhaps my assumption that your energy needs to be expressed is wrong. If you feel like you're holding energy back, than I would recommend to let it out. But if you feel like there is not much to let out, then it is more recommended to do some breathing exercises (or other types of meditation). Or perhaps you can combine the two. Just try them out, and you will see that they will benefit you greatly.

And yes, your work problably has to do with it too. If at your work you feel like you need to shut up and sit still, then it further increases the nervous tension that you feel.
It doesn't necessarily mean that you should quit your job, it means that you must get rid of your excess energy so you can actually focus more on your job. But i'm just making a guess here. You said you were bored with your job, perhaps it could also be time to change jobs, if you really don't like yours. Or perhaps your job is not that inactive, but you just don't like it, i was just guessing.

Anyway, i'll leave you with a link to a video to one of my favorite mentors (youtube mentors can be mentors too), giving you a better idea of what i'm talking about. Don't mind the title, I know you're not depressed (or at least that's not what you indicate in your post), but I think the content within the video can help you a little further.
