Hello everyone I'm M(24),
All throughout my life any conflict or argument towards me my mind would shut off, vision turn into a blur and I would start to feel the need to cry. This also happens in large social situations such as questions in big groups targeted at me, public speaking and any large attention towards myself. 

I can talk to anyone, seemingly fine if the conversation isn't about myself personally, I seem to never have a problem. I'm very easy to get along with and don't have anxiety approaching people.

My biggest issue is the need to cry when I get questioned or speak publicly, I'm not sure why it happens or I feel this way. I've tried to think about it in the moment and breathe deeply or breathe I answer but the same things happen.

Recently I had a training course and the entire time I was so scared to have to talk Infront of everyone, when they asked everyone about themselves just about everyone did a good long speech. I got past my name and occupation and then started to want to cry, the lecturer noticed and moved on. Yet I walked around earlier talking to everyone at the place asking them questions, across desks of people. I can call out and contribute to questions the lecturer raised Infront of everyone, but if asked to expand the same would happen.

TLDR: I can talk and approach people easy, when I get asked questions or confronted I want to cry, even when it's over nothing and it's people I am somewhat familiar with.
