Welcome too to Beyond Blue,
Well done in almost finishing a second year of uni, I bet you be glad to relax after a hardworking year.
Friends can be great and when you find a friend or friends who understands us it really bring great joy.
Simple 114141 even thoe you may not have much success of making friends I glad to hear that you haven’t fallen to peer pressure to be someone who you not as that hurts even more when we try to please people to feel accepted or gain friendship.
This friend who invited you to tea sounds like a true friend that they see more of you as a person and like to speak to you away from the crowd and uni.
Be yourself and enjoy the experience. Take turns in talking. Listen and try to have a laugh. General talk is best way to start. Weather and how busy of a week etc
Also it not how many friends one has It finding a true friend that understands one self.
Good luck. You be fine.
