question: Hiya.. I am a 19 years old female, i weigh about 11stone.. I have a history of TB (4yrs ago) and anxiety (current). I am currently sitting my A-level exams biology, chemistry, maths, psychology and need As as I am applying for medicine, plus the fact that I live alone so i am under a lot of stress. Also my diet has never been great, yesterday I ate a can of marrowfat peas and sweetcorn and today my stools have been mushy and dark green. Since then I have started getting a stomachache, headache and feeling very tired (although this could just be me getting paranoid because of the green stools). Thank you :)
