Why am I so shy around big crowds, but when I'm with one friend than I'm fine?

This is an possible trait of being an introvert like I am. I can personally relate to this issue I’m very shy in front of new people or crowds and I’m very hype and comfortable with my own people. I think this is also a an subconscious way of protecting ourself from any vulnerability. To break this I think you can always mentally have a list of ice breaker topics in with you. If you’re ever put in a situation you need to talk to someone new then you’d able to pick any topic or ask an interesting question that really helps me personally I think it would help you as well. And it’s perfectly normal to feel this way don’t worry but as I’ve experienced this can cause an issue with relating to work etcs hence try keeping some ice breaker questions or topics to talk about in mind. It will surely help.

I think big crowds means a lot of energy, and it's easy to feel overwhelmed in them. Not everyone is geared towards engaging with big crowds. On the other hand, being with one person allows you to channel all your energy there and feel comfortable doing so. You don't have a 100 eyes looking at you and so it feels like a less judgemental space. I think it's good that you know what social scenarios work for you! But also don't be afraid to go out of your comfort zone sometimes (when you feel it's safe to do so), you might end up having some great experiences!

I think is this quite normal to feel that way, we feel comfortable in front of our loved ones as we know they won't judge us if we do/talk something unusual, but we don't know how stranger will think/judge us about anything we talk/do. This is our mind who thinks this way and we resist ourselves to express and talk to others and be safe. We are afraid that what world will think about us, if something goes wrong how people will think about us. But when we start and push ourselves and move out of our comfort zone and face the real challenge (big crowds) then we come to know how much capable we are and how we can move ahead in life.

Hello. That sounds like you may be an introvert, which means that you gain energy from being alone or with very few people and when you are surrounded by many people you tend to exert all your energy, leaving you feeling drained. It is also possible you could be experience what’s called social anxiety. This is when you feel anxious or fear around large crowds of people. If possible try to avoid crowds by visiting places right at opening hours or just before closing, if you your feelings continue or worsen, you may want to talk to your family physician.
