I'm not sure how to get interactions going.

I'm very shy and I met my partner of 9 years at a bar by walking up and confidently introducing myself. Nothing fancy, just some, or maybe a lot of, courage and faking confidence that I did not feel.

I met quite a few people that way before meeting my partner and some dates came out of those interactions. Admittedly, I got rejected a LOT and more than once I went home very depressed, but I met the love of my life, so it was worth it.

Good luck and remember that you are worth knowing and always be polite even if the person you try to start a conversation with isn't!
