I don't know what's going on with me. I've always been a good kid. I've always been nice and caring. But lately I've had a really short fuse and I've made my mom cry multiple times. I don't mean to be so mean. I just get so angry and even small things could set me off. I love my girlfriend, but I've caused so many arguments with her. Honestly, I've tried suicide twice, but luckily I failed. I know I have a purpose, but it feels like I'm going insane. It feels like I'm two different people. I'm 15. Please help.
