Hi, Jazzmynn, and welcome! These can be symptoms of fibro. I have had all of them. When I get nausea, I will eat a little something and it does go away for me. I think because of the pain, many don't even think about when they ate last! But I try to have a little something several times a day.
Be sure to check out the Fibro 101 thread...the first thread on the forum. There is a lot of info about fibromyalgia in there, including a list of symptoms. If you think this might be what is going on, be sure to see your doctor. Many of the symptoms of fibro are also symptoms of other illnesses. Your doctor will run tests to rule out the other illnesses before a diagnosis of fibro is given. There is a link in Fibro 101 called What Else Could It Be. You will see what I mean. I did google your symptoms just to see if they fit any cancers, and I sure couldn't find that. So, I wouldn't worry about that. These are typical symptoms for things like fibro, lupus, Lyme, etc. You will see that in that link.
