I think you should tell your friend, you don't have to tell them everything just tell them what you want to get off your chest. I don't know if my friends care about me but i would hope so because i care about them, and if you think or know that your friend cares about you then you should tell them because they love you but only tell them if YOU love them and trust them. I love my friends and i love making them feel better and you should let your friend make you feel better, cry on there shoulder they care about you! They might now show it very well but they still would love you, and if they didn't then they would have left you way before. And I'm so sorry about your parents, i know you want to give up, which i have tried so many times but there's always that one thing that i always try thinking about, someone might not love me now but someone will someday at some point and they will love me for me and i will feel safe not now but at some point and i don't know you at all but i love you for you. And i wouldn't feel better if you were gone
