Dating sucks and is hard

I have horrible social anxiety so even putting myself out there is so hard. I was talking to a guy for a few weeks which I know isn’t much but now that I reached out to meet in person the timing isn’t right. It’s fine I just feel like anytime I’m actually interested in someone they aren’t in me and it just lowers my confidence even more. I’m Trying to work hard to boost my confidence and stay positive but it’s getting harder and harder to be positive. I feel like I’m never good enough cause no one seems to be interested. Oh and Did I mention I’m literally the last single one of my friends, they are all married/engaged so I just get so lonely!
