no nothing like that has happened
Same thing happened to my daughter recently. After 10 different doctors, it was determined it was nothing more than a flood of hormones screwing with the head. What seemed to help is her spending time with her closest of close friends, and keeping her busy. I'm not going to say what you're going through is "normal" mainly because in life I don't know what "normal" is. But you're not alone in this. I don't think there is even a real answer or miracle cure other than time and try to stay positive no matter how bad/sad you feel. It's not easy, but then again, nothing ever is. Best wishes.
Hi there. When you have these breakdowns that make you cry, can you pinpoint it to something that has happened in your life? Are you overwhelmed with school? Are you being bullied? Something along those lines?
