Dear
Welcome to HCM
We understand your concerns
I went through your details. Symptoms of
depression may include difficulty concentrating, remembering details, and making decisions, Fatigue and decreased energy, feelings of guilt, worthlessness, and/or helplessness, feelings of hopelessness and/or pessimism etc. Depression may also cause many psycho somatic and obsessive symptoms like pain, blurry vision, tiredness, lethargy,
dizziness etc.
But you should be able to distinguish between depression and
Post Traumatic Stress Disorder. As you mentioned, you lost your brother 4 years age. Were you traumatized or deeply stressed at that time? I suggest you to
consult a psychologist /
psychiatrist for proper evaluation and diagnosis.
