During class, look at the people who is sitting beside you and says Hi to them. Tell them your name and start a conversation. That's one of the method to get to know more people.

I have similar situation like you,TS. I'm 22, single and still studying. Before going into relationship, start making friends. People wear mask as they go around facing the world but there will always be at least 1 true friend who's willing to listen to you and hang out with you. Friends come and go, that's a fact. That is why we'd rather enjoy life to share joy memories instead of doing nothing, leaving empty memories behind.


PS: being single without anyone is way better than being single but in love with people you cant have. Therefore, live life to the fullest.
