### input:
why do i have constant feelings of faintness, though I never faint? I have really bad anxiety so I wonder if it is that. When I have these attacks, my pulse seems very slow and weak. I just get really light-headed, faint, weak legs, and then I get nervous. When I eat something sugary, I usually feel better. Am I not taking in enough sugar? I would say I get a total of 15grams of added sugar a day, and thats it. The rest is from natural ingredients like fruit and dairy. I am 19 year old female and active

Welcome to Chat Doctor! I have read your question, and it says that you have anxiety problem, but now you develop dizziness, light-headedness, weak legs, and get better by eating sugar. I think that it is related to your anxiety, or you may be having low blood pressure, as it is not mentioned anywhere that you eat less...so, it is less likely to be related to low sugar levels... From my experience of seeing such patients, I can say that it is quite a common presentation in which such symptoms get relieved when patient takes something sugary/ starchy...and due to this there is weight gain also... If you what to confirm, you may go for blood pressure readings, sugar levels-- fasting and PP, this will tell if you have low sugar levels or not. One may also check sugar when you develop such symptoms... Once the blood pressure and sugar levels found to be within normal limits...please, see a psychiatrist and discuss your problem in detail. Medicine will help you a lot, within few days you will start felling much better. So, see a doctor and get blood test done! In any case, it is not a serious problem, but needs attention. Take release ask if you have any other query
