Is it normal if people ruin my day?

Idk if I'm anti-social because I do like to talk to people, meet new people, etc but for some reason, when I'm just surrounded by people and observing how everyone is, it just makes me depressed. I'll watch tv or read stuff online about people in general and it doesn't surprise me how they are but when it comes to actual in-person, I can't believe how all these things I watch and read are true like people are actually like this? Overall, it just comes out as unauthentic. Sometimes I want to get out more often and mingle but then I start debating after all these observations like do I really wanna bother and be around society? Also, when it comes to work, I might come off as a debbie-downer or slacker but honestly, I like what I'm doing, I have a passion for things, but then when people get involved, they just kill it and I get all down and stuff and might rub off while I'm working or just in any environment. They suck the fun out of everything. Idk what I'm going to do because I'm young (22) and have to face reality eventually and unfortunately that includes coming to face with human beings. But like i said at the beginning, I do like to go out. I guess I'll just keep doing what I'm doing and thats being reserved and keeping to myself. I don't mind going to eat alone at a restaurant I really don't give a crap and people make a big deal about it. Or now that we have social media, you see people saying these things that I wish were true about them, or post quotes that is true and try to use it to define themselves but in person, it's a different story. I think everyone is scared of each other and thanks to social media, we can express ourselves who we really are but in our comfort zones which is good and bad. Once you get out in person, it's like you're afraid to express your social media self because they most likely will make fun of you. So everyone turns out fake and I just don't trust people so like I said, I think I rather just continue to keep to myself. I have friends but hang out with them usually one on one. I still like meeting new people but that's it. Like hi and bye.
