Answer: Get out of your shell and talk to people. Also it never hurts to try anything, because at the end of the day you can say that you tried at least.
Explanation: Well i know how you feel and i've been there in the past. Honestly talking to people requires a lot of mental work. Like I use to be a introvert but now I'm a extrovert and it really is tiring just to talk to people. Learn how to get out of your shell. Talk to people, what really helped me was hanging out with loud friends (talkative) and eventually i changed and quit being such a introvert. Don't be scared to talk to people it's not too hard. A simple "whats up?" or "hey" is good enough to start a convo. Also don't be so dry when talking and what I mean by that is like for example. "Oh hey how was your day?" "it was ok" "You have any plans for the weekend?" "idk". For goodness sake don't ever be like that, like no one wants to talk to someone like that. But just try to get out of your shell and talk to people. Try to jump in convos (not rudely). Sorry there's a lot to say but yeah you can understand.
