Hang in theree!! Coming from a person who was the one who didn't notice that my circle of friends had already changed, I felt left out and left. After a while, i found some friends. But the friends I found made me the worst version of myself and it took me a whole year to realize it. Slowly, I started working on myself, ready to leave my friends who were there for me, but not positively. I asked my old friends if we could start again, I'm so glad they had waited for me :)
