outspoken

So today I was at a college open day and I was with my parents, I'd registered and just waiting for the introduction thing to start. My dad kept pressuring me to go and ask someone where we had to go, I went up to someone but they were told by one of the organizers to go get ready for campus tours so I went back to my parents. My dad told me to go to another guy to ask but I just wanted to wait, it was pretty intimidating with all these people and he just goes 'you need to be more outspoken'. I get what he means but it just really upset me, I've been through some things that have knocked my confidence but I still get out and lately been doing things I usually wouldn't have done. He usually says snidey remarks so it's nothing new but literally after he said it, they announced where we all had to go for the intro. And I sat through the first 10 minutes trying not to cry. I'm on my period so I'm extra emotional. Is it stupid that I feel like this? I try to be confident but I can't just flip a switch
