I Lack a Sense of Family With My Family

So i'm trying this shit out

So to put it simply I hate my family, and most of all my dad.
For every little or moderate mistake I make or imperfection I have I get yelled at and badly insulted by him. For my whole life. Now I stay on the computer with various online communities for most of the day because this upbringing made me too scared to confidently do anything in my life for fear of failure/punishment. Online anonymity for a person like me lets me be myself more confidently, and I'd say I'm a generally very friendly and kind person. I'm not necessarily socially inept or anything, and I have a few friends (who are busy most of the time), but doing grown up things that I should be doing at my age is very hard emotionally for me, and naturally now I have fears about my inability to live in the real world.

The rest of my family members (sister and brother) are similar, but not as bad. My mom is ok.
So you know, give me some emotional support or words of wisdom or advice or something here please.
Thanks for reading
