Hello.
A feeling of sadness of mood for a significant period of time, which affects you day to day life can be associated with depression. However the other symptoms need to be evaluated by a mental health professional such as a psychiatrist. The diagnosis can be made only after a careful clinical interview and examination. You might have something more then just depression. Please consult a Psychiatrist for a diagnosis. You might not get an accurate idea about diagnosis via online conversations.
Hope this helps.
