When you have parents who are deeply unhappy with themselves, you don't get to see what it is like to be happy.
You don't get to learn what happy people do. You identify with your parents because they are your role models. You emulate them consciously and unconsciously.
Sometimes your role models are so poor that you are not given enough positive regard that you need for self-acceptance.
Are you doomed to continue the same miserable life ? Can you realize that you are not your parents?
It doesn't matter what other people think. It doesn't matter if you make money. It does matter that you take your own goals and dreams and find a way to make them real.
I believe we all have certain gifts that can be used to better ourselves and others. We can say to ourselves that one day we will have the time to pursue those goals and dreams and maybe that is true. Maybe we do have to wait until we don't have pressing bills to pay that depend on that steady paycheck from a job we tolerate.
