15f. Im desperate at this point

I dont want someone to dm saying wyll then just vanish. Im asking for friends and some people do talk they ghost not even a day later. I barely have any friends because im introverted. I get shy and anxious when im around people. I dont know how to open conversations. And that resulted in me being one of the loneliest girls in my grade. Please be my friend you can be anything but just know that i cant start conversations
