Dealing With Social Anxiety

I am not a people person. Despite being a YouTuber and now a “professor”, I would much rather be away from people as much as possible. Of course, that’s not very healthy, so I try to put myself out there as much as I’m comfortable with. But each time I have interactions with someone else, I get very anxious beforehand. I deal with it because I must, but it’s something I’ve felt basically my entire life. The thing is, most interactions, especially those with friends, go well. I have fun talking to my friends and even people in the community. After the interaction is done, I’m almost always happy that I was there to take part. But I still feel anxious every time, even if the time before went well. I’ve found no real solution for dealing with this other than sucking it up and following through. When I need to do a podcast or have a meeting, I just do it. I have a good time and I’m happy and relaxed until the next one, when I’ll inevitably freak out again. I’m not sure what causes this…
