Hello, My name is Michael. I am 21 years old, perfectly healthy (or I think so)

I have been feeling tired lately. My sleeping is kind of out of whack, it usually going from 3-am to around 11 am. Today I went to sleep at 3, but woke up at 9, I was feeling much more energized.

I also have a weird diet. I eat maybe a couple hours after waking, then eat again a few hours after that, and again after that. I am more energetic when I eat more often, as Im sure anyone would be.

I exercise fairly often, but since having my hand and ankle injured, I havent exercised in about a week or two. It is actually making me feel more tired.

The reason I am here is because I am tired, I have random ringing in my ears, and headaches.

When I wake up, I do not have any headaches.
I do wake up tired though. I may be depressed.

Last night, my room was silent. And my ears were still ringing. I had a headache also. Is this something I should be worried about?
The headache felt throbbing. In fact, it felt like I could hear my pulse from my neck.

any insight would be much appreciated. :thanx:
