I'm having some strange psychological complications, can you help me get my life back on track?

About five months ago, I suddenly developed some strange psychological problems. Feel free to read my other question on them, just click on my user name to find it. In summation, I began experiencing some signs of an anxiety disorder, but I wasn't anxious. I've had ADHD all my life and the psychologists also thought maybe I had ADHD and OCD also. Finally, they ruled that out. Now, I don't have an anxiety disorder, and I don't have OCD. Currently, I'm undiagnosable.
My symptoms:
I feel like there are a bunch of people in my head, each has his or her own likes, dislikes, pet peeves, general disposition etc. They are just like real people. It feels like DID without the memory loss, I'm always fully aware of my actions so I don't have DID. I don't even know what I want anymore, because any minute I'll want completely different things.
I have all of the symptoms present in ADHD.
I have recently developed Tachycardia and with it shortness of breath and palpitations.
They took me off Concerta, my ADHD medication, and now I am extremely fatigued and sleep more than half of the hours in a day falling asleep during tests etc. (Not in a narcoleptic way though).
I also am experiencing what I call my "freak outs".
Some small stressor will trigger an enormous reaction in which I resort to extreme behaviors and also switch rapidly between my "people" making me unable to react to and solve the situation. I will very rapidly shift from sobbing, to violence, to stoicism, to indifference, to blaming myself etc. etc.
Some freak outs involved me punching my car to the point that I've had bloody/swollen knuckles for quite some time with blood stains in my car. I've also driven away and refused to disclose my location. Sometimes I scream and shake and sob(this is done in an excessive, extensive, and inappropriately timed manner). I have many holes in my wall, one is so large that my biggest poster cannot cover it fully. I walked out of my house in bear feet in snow and would not come home. I sometimes sit in my room for hours with the lights out staring at the wall. Sometimes, to calm down, it helps me to draw my mind doodles where I try to doodle what's in my head. I can't describe what they mean in words but every doodle corolates with feelings and thoughts in my head at the time. As you can probably tell, my reactions varry greatly.
I can no longer funcion in my life. I'm wrecking my relationships with everyone around me, family, teachers, my boyfriend etc. (I have two questions also dealing with me and my boyfriend through all this if you want to look at those). Also, I'm normally a straight A student, but now I'm making B's and C's for final grades and this can't go on much longer or I'm going to hurt my GPA. I really need to keep it high so I can get into the college I want to, I don't know where I want to go yet, but I want to get in wherever I want to. I am weeks behind on the assignments in all of my classes, scared of neurofeedback and scared of trying more pills because every time I do I get messed up even more. I can't take this anymore. I just want to know who I am and what I really want. Its really, really scary to not know who you are. I want to fix my relationships especially with my mom and boyfriend and also I want to fix my grades. Please, please help me. I have so much to deal with and no time. I just feel like I'm falling in a hole I can't get out of, it's suffocating.
Thank you for listening,
Mia<3

You need to find a counselor or doctor you can click with. It sounds like Bi polar with other issues.

You need the right meds and treatment, I suggest trying a new doctor and getting a complete physical. Also ask for Cat scan amd MIR.
