Can someone tell me the difference between mania and just pure anxiety? And do stimulants cause it to be worse, like coffee? Do you have the desire to do so much, but have the inability to just focus on doing it? Do you feel like you have this hum inside, nervousness, but not exactly?

Keep pacing the floor but not no where to go? Keep checking things over and over, even more than usual? Go in one direction to do something, but maybe forget it halfway through, and start on something else? Forget things more easily, just simple every day things? Find it hard to even get dressed or decide what to do first?

Do you choose to maybe eat something or pop a pill or anything, just to have a focus, even if you're not hungry?

Any perspective would help.
