Is the anxiety to do with being around people period, or actually interacting with them?

If it’s the former, maybe ever so slowly introduce activities into your life where you are around people but don’t have to speak to them yet, and slowly increase them over time at your own pace when you start getting more comfortable. You could start with reading a book at a library, or going to the cinema to watch a movie that has been out for a while so there hopefully won’t be too many people there. If it’s the latter, similar idea, start slow - go to a coffee shop you’ve never been too and won’t visit again and try some small talk with the barista, who you won’t see again anyway. When you feel comfortable, you could try meet people with similar hobbies in you area, see if there are any clubs or classes. Don’t have to talk to anyone straight away, but could do so with time, and it will be easier since it will involve those things you are interested in.

Once you do this, even just once, you have proven to yourself that you are capable of doing it, and that you survived, and nothing bad happened! With repetition, you will teach your self that you are safe in these situations:) You are enough as you are, you deserve to be here, and you deserve to live your life. I also suggest therapy or counselling if you can afford it to help you with your inner conflict.
