Hi... Based on what you have shared above I believe your presenting issues are a mix of your childhood trauma (witnessing parental-marital discord) and your immediate stressors (career, marriage, kid, dreams, expectations from self & significant others, etc.).
You are experiencing a dichotomy of what you witnessed as a child in terms of parenting, marriage, child rearing, etc., in context to what you are able to create now as an adult.
You are experiencing a mix of emotions which are directed towards your parents at a superficial level but actually a deeper reflection of how you felt as a child and how you feeling now as an adult. This contrast along with your immediate stressors are making you feel so low.
These kind of issues typically take 1-2 years of weekly counselling sessions to address from the root. Your immediate symptoms will get recovered within 3-4 months of weekly counselling but if you leave the process of therapy in-between just because the symptoms have got better than they are very likely to go latent and reappear later in a worse condition. I always recommend treating issues from the root and not just from the surface.
