Yes, it's a medical condition. Some people don't realize it because it slips in through emotions and the way your brain thinks I'm a teen and I have it so I know what it's like. Always tired and loss of appetite are triggered by this.
Also, the cyst could as take metal tolls as well. Medical conditions lead to depression as well. The nauseousness could be due to taking the medicine, vitamins and the loss of appetite.
Not eating can lead to nauseousness more especially when on medication.
I had a cyst on my ovaries as well, you might need to check in with your doctor about them. I waited too long and I had the same problems as you, I was always tired and sick. Then I had to have emergency surgery.So be sure just to be safe make a doctors appointment soon.
I have endrometriosis and ovarian cysts and they cause you to be very tired and fatigue! Try to get 8-9 hours of sleep a night and if you can take 20 min nap during the day. It will help.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
