low self esteem & cant believe in myself

Hi, I'm a woman in my 30s. I grew up in a depressing, dysfunctional household. My family has never shown me love or warmth, so I can get annoyed easily at times. I am called a "crazy" or a "mentally unstable girl" by my parents. This is the result of their upbringing. They had no desire for children. All I got in return from them was pain. I can't be vulnerable with my parents. I was an exceptionally intelligent student in school. I am a very intelligent person. I can excel in any subject I choose. But these labels from my parents are too much for me to handle. It makes me doubt who I am and kills me from the inside out. How can I get out of this situation and do the best to stand out in this world?
