Hi. I went through your query in detail and understand the problem that you must be facing. All your symptoms can be part of a depressive illness. Many a times, unexplained body aches occurs due to stress even in absence of other depressive symptoms. Your episode of unconsciousness can also be explained on the basis of underlying stress. I would suggest that you seek a psychiatric consultation and get evaluated. You will have to be patient about the response as it usually takes few weeks to start showing any response. Adequate treatment with medications and psychotherapy can help you ease out your problems.
Next Steps
