Can't make new friends because i dont know how to socialize?

Back when i was in elementary school, it was so easy to make friends. Now its almost impossible for me to make friends. I just stay in the house on my phone now because of it. Im too scared to go out because im not confident and my self esteem is low.

Like when im tlaking to people in person,i can NEVER thing of anything, i try texting and i think about stuff but its nothing interesting to the person, then i HATE talking on the phone. If anything i talk very fast on the phone and i NEVER can figure out anything.

People always say talk about anything, but my child hood isnt interesting at all because it was pretty much bad. Im in high school now and i still have nothing going on in my life. I literally can talk abotu anyhting, i dont even watch tv, i just watch youtube or play clahd of clans or clahs royal.

I only feel comfortable on social media, but once im talking to someone in message chat i get too scared. All i say is "what are you doing"or" how are you doing"i need help!

Maybe like things you talk about with your friends,because this has been like this pretty much all my life. Anyone has tips or tricks tp fix this
