I realise that none of my friends text me because I’m too soft spoken and too quiet. How do I fix this?

I have friends as you are all aware but they never text me but talk to me in person. They are also texting eachother. This is what happens in every friend group I’m in. Please don’t just tell me to make new friends because I’ve tried to and they are doing the same thing to me. Idk why but there’s something about me that puts everyone off me. It could be because I’m too quiet, or maybe because I have autism. I’m just fed up of seeing my friends have loads of texts and even texting each other but not me. What am I doing wrong because use everyone does the same thing to me. Is it really just because I’m extremely quiet and awkward.

I just don’t understand because in person it’s going fine but it’s just that they don’t text me and it’s the same story for my college friends my school friends and even my fucking cousins. Is it because my social anxiety makes me seem desperate and am I trying too hard? I never had this issue a few years ago but since then I’ve been stuck in the same issue.
