I need input, how to cope and end my problems, please?

1. I have a horrible craving for self-mutilation but I've been trying other things then cutting/stabbing w pins/ burning/ scatching etc. to deal with how I feel like drawing and writing it out but it just increases my wanting, and when I draw it out... it's just the same horrid words I hear in my head over and over again. 2. I've become very introverted and supposedly bipolar. My emotions are haywire, one moment I'm happy energized back to being able to fake a smile and then next it's like I'm ready to die and can't be pulled out of it. No1 around me seems to understand or wants to know. 3. The slightest yelling or touch I get from someone or just constructive criticism puts me on edge. All compliments feel like theyare just lies and it hurts. 4. I have momentary flash backs that send me into silent crys and shaking. Idk how to stop it but I am able to cut it short and keep going after a minute. -background on me: I'm 15 a sophmore almost junior , abused verbally almst reg. and phys. evry so often 4 past 4-5y
