<human>: Give me the gist of the text in a nutshell

I am still living at home with my parents while I finish my undergrad studies (late beginner) and it has been a blessing for the most part, but on the other hand I can't help but notice the absence of any substantial relationship with my dad. 

It has not always been strained with him, every six months of so he wants to hang out and I feel like I can connect with him somewhat, but for the most part I don't even really feel like he's my father. 

I am not completely blameless, I used to be a real big fuck-up. I did pills all the time and it made me into someone that I'm not. But I sobered up and turned my life around and I've done a lot to try and right my wrongs. I even got a 4.0 at a local college and just got accepted to transfer to a big private university. 

But still, the only times my dad wants to talk to me is when he wants to insult me. Don't get me wrong, I know he probably says some things in jest, but I feel like sometimes there is a genuine insult behind them. Like for example, when he completely trivialized my depression and anxiety issues. He said that I have "nothing to be sad about" and "it doesn't make sense" or that I'm being overdramatic. It's disrespectful and when I try communicating this to him, he completely shuts it down and won't hear it. If I cry or if I get upset, he just laughs at me. 

His relationships with my sisters is so different. He is always excited to see them and he engages them in conversation. He shows concern for them and is always supporting whatever they do. He is so proud of them and I can't help but be envious. I feel like the black sheep. Totally unwanted.
<bot>: I have turned my entire life around to make my parents happy. I just want my dad to be a real dad to me and I don't know what else to do. Help.
