Today my parents had a discussion about buying a house. We tried to buy a house for quite a while now and it hasn't worked out mainly because we all have different expectations. Whenever my mum shows him a house he that he doesn't approve of he is pissed. It happened a lot of times that I showed him a house and he replied are you out of your mind or did something hit you on the head or if you and your mother buy that house I'm going to hang myself.

The discussion was uncomfortable and I don't know why but I started to feel weaker and weaker during it and started to shake and go cold. My mum said that I went incredibly pale.
Thing is they wanted me to speak and I just couldn't and then I basically shrieked and started to breath very fast and heavy. I got dizzy too. It felt like my body automatically took those really loud fast breaths and I couldn’t do anything about it. My mum wanted to call an ambulance but my dad didn't want to. I then started crying. They asked what's up and I just burst out and offended them. 
Since then my dad is pissed at me and has been ignoring me.
I don't know what to do. I know my reaction was inappropriate, but my dad offends me on a regular basis. I just don't want another confrontation.
