Since I was 18 years old I've had this same issue and I'm now 21. I have this intense fatigue all of the time along with a shortness of breath, my lungs never fill correctly it feels like. Along with a heaviness in the epigastric region. Right where my stomach is. Ive gone to the doctors over 100 times and have never gotten an answer. They've done blood tests and never told me i had cancer. Tested my liver, kidneys, lungs, heart, and etc with blood tests and those came back normal. No ovarian cysts and no bladder cysts or stones. No diabetes. No anemia. No thyroid issue. Got tested for hep c today awaiting those results. Yet no doctor ever has an answer for me they just say I have anxiety and to come back. Ive desperately been trying to seek help since I was 18 and it feels like I'm nearing my final days. I havent been to work in 3 weeks I cant even move around really without being completely depleted of energy ive gotten way paler than usual and I can never get a full breath of air. Trying to explain this to my fiance is frustrating because she doesn't really understand how physically debilitating my exhaustion is. I need help so bad. I want to know what's wrong with me because no doctor seems to know. I was told by my fiances mom to get a rheumatologist so that might be my next step. Does anyone have any suggestions? Please.. i can't live like this anymore.. im 21 and I feel like I'm on my deathbed.
