Do you understand that your father is at the bottom of all your troubles?

I'm glad you have this Something! It's telling you the truth.
but indeed some part of me says I'm a failure
I have quite a pathetic life style and I'm exhausted
I understand all this, too. When you were a little boy you believed the things your father taught you about yourself. You had no choice then, because you were dependent on him and your mother for everything. That little boy has never really gone away, and he still thinks his father must have been right even though your adult self knows better. So it's the abused little boy who feels like a failure, not the adult you.
As far as I know you've had a good job for years, which means your employers and co-workers think better of you. They probably think better of you than you think of yourself.
I am sending you a great big hug, from someone who understands what it is to have an abusive parent.
