[|Human|] I don t know if its worth seeing a doctor or not. But I always feel like I m never getting enough oxygen and my heart races a lot, even if I m just sitting down or trying to sleep. Sometimes my vision will fade away and then come right back. And I get confused or like a dream state. Tired all the time. I m starting to sleep 12 hours and more, and can still take a nap. Even though I sleep a lot I now have dark circles under my eyes. I have a healthy diet. I never eat fast food. And watch what I take in. But I m slowly losing weight like crazy! I m 5 6 and 107 pounds. Any clue what could be wrong?
