It is so incredibly painful that my brother is the golden child

I live with bipolar, and my life is a miracle. I work full time in tech. I’m a solo mom to a 6 month old. I fought so hard for this life. My mom has had me blocked for 3 years. She knows I have a baby, still won’t unblock me. My dad openly favors my brother. His nickname with my family is prince. When my parents got divorced I was 13. I lived with my dad full time. I immediately had to do everything for myself like laundry. My brother didn’t do laundry until he left for college. Literally everyone saw how much my parents favored him. It’s so incredibly painful.
