I could be really defensive

If someone asks me a question like “So do you wear contacts just because you like them, not because you need them” I right away take it offensively, even if they’re just asking a question & I know its a flaw of mine, but I’ve been trough shit that has made me that way. Before, if someone asked me a question like that I’d answer it normally, but I’ve been trough situations where the person is trying to humiliate me with questions and snide comments like that in person and in real life situations and of course on the internet, that has made me so defensive like that. I try and control it at times to not come off like such a bich, but its just one of my flaws.
