The symptoms that you are experiencing when being in a building or near a building, may be panic attacks. You may have a condition called claustrophobia.
It is irrelevant that the other students do not have the same symptoms than you. What is important, is that you have symptoms and feel unwell when in that room. It may be that it is because of some of the chemicals that you are more sensitive too than the others, the fact that here is no ventilation, no window - and also it may just be that you feel overwhelmed being in a confined space.
With regard to your symptoms with your short term memory and being lost for words, make an appointment to see your doctor. Sometimes these symptoms can be due to a urinary infection, lacking in Vitamin B12, being anaemic (having low iron levels), lack of sleep, stress or depression, sometimes cardiovascular problems.
It is highly likely that your symptoms are due to lack of sleep and stress with all the college work that you have. But you do need to get checked out by your doctor to find out for sure so that you can get the appropriate medication if this is needed.
Make sure that you get adequate sleep and eat a healthy and well balanced diet with lots of fresh fruit and veg. Cut out or cut down on processed foods, cakes, biscuits, fizzy drinks etc. Make sure that you drink enough fluids during the day. Being dehydrated can also make your memory be not so good. 2 litres of water a day is usually recommended, but you will need to drink more if you work out and sweat.
If you wish to stop smoking, ask your doctor for help. In the UK a doctor can help people to stop smoking. One cigarette contains 92 carcinogens, not to mention the cost that I am sure you have better things to spend your money on.
Lymphoma usually presents with swollen lymph nodes and you will know how your sister was when she got diagnosed with this. But if you are concerned, you should speak to your doctor.
Let me know how you get on.
Best wishes.
has your sister been tested for ebv new research has shown that it is linked to hodgkins and other cancers .almost everyone has it .generally it does not cause symptoms.but it can be chronic if your family members had it there is a good chance you would .chronic epstein barr can show these symptoms or a recent infection.also over time ebv can make your neutrophils go low . just wondering if anybody was checked for hereditary immune disorders .weaker immune systems sometimes have a lower resistance to allergens .concrete buildings ,underground structures tend to be a little more damp and probably harbor greater concentrations of mold.could be a possible explanation as to why you feel the way you do while inside these non breathable buildings.so it could very well be a mold allergy if it is only happening in concrete buildings.
just a few scenario's to consider sounds like something you want to present to your doctor .hope you can find an explanation.good luck mogirl1.
