Why am I so alone?

I’m in my early 20s I should be living life right? But instead I’m stuck here think what is wrong with me and why am I so alone? It seem to that no one want to be around me or do somethings that I like. I’m a person who likes to try new things and explore but I don’t want to do it alone. I've try being in the mindset I can do things by myself but I’m honestly scared to do it. I’m antisocial and have bad anxiety but still wanna leave the house a few time a month to do something fun but have no one to do it with.
