I’m 17 now but once when I was... maybe 15-16, I had been so sad that ending it all crossed my mind. But then my best friend told me that I should just ignore those bad things and focus on what makes me happy, she moved me from depressed and sad to happy and vibrant. Two weeks later me and her started dating, and I moved in with her and I’m truly happy
