I hate my family!!

My family is always unfair to me. When I got pregnant with my son I didn't really know my bf yet but he stuck around to support my pregnancy and be there for me. Well my dad would talk shit and say that I was gonna be a bad mother and I need to practice holding a beer in one hand and the baby in another. :( . Well my sis found out she's pregnant again but with a different guy she only knew less than a month and my parents were all happy for her and didn't say nun bad to her. Ugh why do they do this to me I'm tired of crying and caring.
