Hey there!
I'm sorry to hear about what you're going through. I can relate more or less to it. It can and will get better though. Sometimes parents just don't really know what to say or do when it comes to situations like that but that doesn't mean they don't care or love you. I've also lost many friends in my life and although it hurt to lose them, I came to the realization that they most likely weren't true friends, and if they were, sometimes taking a break is a good thing and they came back around. All and all just keep your head up, things will start looking brighter.
