I know EXACTLY what you're going through. I had a father that would belittle me in front of my sister (his favorite child) and make comments about my complexion (I had acne when I was a teenager), call me names and whatever else. It scarred me emotionally, shook my confidence, and made me feel like a worthless individual. I'll never forgive him for that.

I "overcame" it on my own I suppose. I got a good job, got a married and had a family. In a weird way I thank my father because when my kids were born I knew exactly how to NOT treat them. You might need a different approach. Not sure. Just remember that you're a human being and ALWAYS worth something to somebody. Don't let the negative people get you and keep you down.
