Hi Yajaira,   I'm sorry to read that you are having this bad patch. What is unusual about your question is that fainting in relation to worry/anxiety/panic tends to be a major concern but doesn't actually happen. The reason for this is anxiety will increase blood pressure whereas fainting - and by fainting I mean actual loss of consciousness not feeling faint or dizzy - is really only to do with low blood pressure.   There is however a condition known as 'vasovagal syncope' in which a highly emotional experience can lead to a reduction in heart rate and a fall in blood pressure causing the person to faint.   It may be that you may be forming an association between your mental and physical state that doesn't actually exist, simply because you are trying to explain what is happening to you. Or, the way you think about fainting is different from the way I've just described it.   In terms of blood pressure I wonder if you've thought of getting a home blood pressure kit or maybe borrowing one from a friend. In this way you can monitor your own blood pressure at different times of the day and report your findings to the doctor. If you do have low blood pressure the times you will feel faint will be if you stand up rapidly after a period of rest, or if you exercise.   Otherwise, feeling dizzy and faint is very commonly associated with anxiety and particularly with panic.   I hope you manage to get to the bottom of this and that my answer helps things along a little.
