I was doing pretty well for a while. My coping skill was eating(more of a mechanism) and it was helping me a lot. Now, I can't even stomach anything. The closer the trial is getting, the more my depression is hitting me. It feels like I can't distract anymore. I can't even look at anything with a razor any more. I feel so sick. Some one please help me.

Okay, I've been searching for help. I have a problem. Let me start from the beginning.
My eldest brother suffers from cerebral palsy, and my entire childhood- my mom did not stay with me (parents are not separated) and my dad isn't exactly the loving type.
I have been a liar (without meaning to) from my childhood, and I have been sexually abused when I was a child (it didn't feel like an abuse, though)
Growing up, my elder brother (another one) kept dominating me or comparing me with my cousin brother who stayed with us. My brother would even force me to do things I didn't want to. He literally used to twist my arms.
Slowly, I feigned love for him. It happened on it's own. I actually believed myself. I knew I found him irritating and unwanted but still I respected him.
The somewhere around highschool, I got into a relationship and got cheated on. Yes, it was my first love.
It hurt. I was in a boarding school, I felt alone but never cried. I tried to take my life for reasons I can't remember. That phase of my life is a blur.
I thought everything would be okay.
It didn't.
My dad took me to a therapist, but my mom felt I was possessed by a spirit.
I'm 16 now, but I still haven't rebelled or gone against my parents.
Anyway, I never met the therapist again but I had to take part in rituals and what not.
Back to my brother, he manipulated me and made me look bad in front of my parents.
Being the weak, submissive sister I was, my parents never thought it was my fault.
Moving forward, he even made me lift up my shirt because he wanted to see my body type. I was obsessed with losing weight, I was dumb, I did it.
Now he would hug me weirdly and said I never hugged him properly. It sounds funny but he said my butt was too outwards, it should be inwards towards the person I was hugging.
Now, back to my elder brother, I know that he is suffering. But he does so many things to get attention. Shouts, screams, cries all day long. I'm suspecting that he even feigns illness. It isn't that we don't love him, we do. We do everything he asks, but still...
My father has never been affectionate. But he has always been there for me. We're good friends.
My mom, I don't know. She always makes me feel that marrying dad was a mistake. We're good friends, but... I feel trapped. Everything I do has to be under her.
I can't do anything on my own.
I feel suffocated.
So, around five months ago, my elder brother died. He was an alcoholic. He hit me, we fought. I never spoke to him again. I guess, I never will. I hadn't seen his face for a week or so, and when I did... I knew it was lifeless but it didn't look that way. I can't accept what happened. I'm angry that I couldn't be angry at him anymore. I don't know.
Now, I'm rude to people. My teachers say that I have lost that shine. My writing suddenly improved. I can laugh but still I feel different. None of my friends talk to me. I only have online friends.
I feel so alone.
Sadly, I think I like it that way.

What is your definition of psychology ?

...

I self harmed for two years. I began starting a new coping skill that has been really effective; eating. Although, I'm worried because I had a slight eating disorder before, eating might draw me back in it agaian.
