I dont know anymore

Im a 14 year old girl that just feels stuck. I dont know what to say or think, everything always comes out wrong. My family doesnt seem to understand, my friends only say what they know i want to hear. Ive been feeling this way since I was eight and i just dont know what to do anymore. I use to hurt myself just for someone to notice and see (just for someone to care that i got hurt) it soon became a habit every once and a while i would go to my mom bathroom, lock the door and cut whether it was my arms my legs my face. Yet my family didnt bother to care or notice. No one understands me, i feel like this is my only hope of getting better, i want to know that people care. Ive been tired of doing anything lately. Everything and anything makes me upset for no reason. Ive been trying going on walks and working out. I use its kind of working, i just think i need someone who understands me.
