I think I maybe hae Bipolar Disorder, I'm only 15 years old. I'm unsure if its just may age but I also have Social Anxiety so I dont want to tell anyone about this, not even my family. I'm getting suicidal thoughts and feel completely hopeless and useless but other times I'm really 'high' and happy, its not as if I go from one thing to the next within the snap of fingers just like within 30 mins or something. I also feel Fatigue with loss of energy when I've had 10 hours sleep. I feel like I'm pyshically slowing down. I'm finding myself being bored with the things I used to always find fun such as playing video games. I hope this helps, I'm defently going to the Doctor when I'm 16 but Right now, I'm to scared and feel alone.
