Am I the asshole for not inviting my bio parents to my graduation?

(Twilight x Hannibal crossover)

I, 18 female/male/enby, ran away from my abusive parents (Renee 35 and Charlie 40) and older sister (Bella 19 female) at age 8.

I was then LEGALLY adopted by a nice couple, Hannibal Lecter (age 43) and Will Graham (age 37), who already had another adopted daughter, Abigail (age 19) after my parents signed over their parental rights.

Flash forward 10 years and I'm graduating high school with colleges (Harvard, Yale, Stanford, and MIT to name a few) offering me full scholarships and successful companies offering me internships. My dad and papa are so proud of me and my big sister has been helping me figure out which college I'd like to attend.

The problem arose when my sister took me shopping for a graduation outfit. We accidentally ran into Charlie, Renee, and Phil (Renee's new husband) who were shopping for wedding gifts for Bella.

They started badmouthing me and insulting me. I tried to leave and deescalate the situation which was making my sister furious. Abigail wasn't having it and went off on them after they called me a 'failed abortion'.

She told them everything and went on about how schools and wealthy companies across the globe were trying to buy me (which is true but I didn't want THEM to know that). She then asked what Bella had been up to and as it turns out she was marrying straight out of high school and wasn't going to college (mainly because she drained her college fund to pay for dirt bikes) and planned to become a trophy wife to her high school boyfriend.

They got real quiet then as if they just realized that they messed up.

I dragged Abigail away and we canceled the shopping trip for another day. A few days later we rescheduled the trip with our dads, but when we opened the door to leave we came face to face with my biological parents.

I don't even know how they got our address.

They then went on this long speech about how they decided that they want to be a part of my life now and how much they missed and loved me and were so excited to be a part of my successful career. I didn't really care to listen. I was looking for a particular sentence in their little speech and when they didn't say it I asked;

"Is that all?" To which they responded with a confused "Well, what else is there?" I then said "Well how about an apology for how you treated me as a child?" To which they scoffed and said they did nothing wrong, that they were 'disciplining' me.

I blew up at them and showed them the scar that they left on me as a part of their 'discipline'. The marks on my back from Charlie's belt buckle, the scars on my wrists from when I was handcuffed to the stove for the entire winter break while they were on vacation, and the cut on my leg from when Renee chased me with a knife because Bella came home with a broken nose after falling face first in ballet classes (which I never attended).

I told them that they weren't welcomed in my life nor were they invited to my graduation and that if I ever saw them again then I would call the cops and file for a restraining order.

Now Bella and them have been blowing up my phone and calling me a self centered bitch and an elitist asshole. I feel bad for losing my temper, but was I wrong for blowing up at them and not inviting them to my graduation?
