Hello.  I hope you are aware of the policy that we cannot diagnose online. But I can give you some ideas to think about. Your symptoms can be part of a depressive disorder. It could either be Major Depressive Disorder or Bipolar Disorder. But you may need to think beyond depression. Features of adult ADD (attention deficit disorder) can present like depression. However, these are hypotheses. Your actual diagnosis can be given only by a mental health professional who can interview you and evaluate the symptoms.  It is important to figure out if these problems are recent. And if so, you need to see if there are any particular stress factors associated. You may need to work on relationship issues, especially with your parents and your beliefs about marriage. This can be effectively done in psychotherapy sessions. You can look up Cognitive Behavior Therapy (CBT) or Rational Emotive Behavior Therapy (REST).  Hope this helps. Take care.  Abhijeet Deshmukh, MD
