Small talk is difficult for lots of us, so you're not alone, trust me. I find that small talk is a little easier if you're around people in a setting like a volunteer opportunity, then you can talk to them about what you're doing in your volunteer role. Also, if you have hobbies, maybe consider joining a group dedicated to that and see what happens.

The most important thing is to not stress about it too much. I know that's easy for me to say and not so easy for you to do, but the second a person starts to stress out, they can't focus on trying to have a conversation.
