I'm going to drop out of CS and start my own app dev then branch off to cyber security.

I need a decent laptop to run kali linux and a workbook which i can write code.

Parents wont buy me a laptop a workbook which i can code and do my cybersecurity work.

My parents dont give a fuck about my business ideals nor ever calls me or gave me very little financial support.(maybe 3000 dollars max in my lifetime)

Also my mom is a fucking bitch who can't stop nagging and my dad expects me to take care of him when they are older.

(he wants me to buy him a lambo).

I also had mental issues in the past and when I bring it up, they just dumpster on me.

I have given them alot of respect because they are family but they bring absolutely no utility to my life and are leeches and do nothing but drag me down.

I have come to the point I do not want to ever associate with them ever again and cut them out of the life.I couldn't care less if they died tommorow and would have no remorse.

I need some advice before i burn the bridges.

Thanks.

Background: im 21 year old asian male living in oceania while my parents live in asia. My family is affluent and no financial problems.
