Please, Help me!

Hello.
Firstly, sorry for my easy english.

I am 20 years old, male.
I am 111.4 kg and 175 cm height.

I have serious self confidence problems in social life due to my weight i guess.
For example, i dont have even 5 friends in my cell phone at this age. I dont remember when last time i went to outside.. No one said i love you to me in my life never.
I feel big shame due to how i look like. I feel like everybody will reject me and judge me due to how i look, i feel like **** and humiliated seriously.

I wanted to change everything.
In 2010, i did a serious diet with my own mistakes. In months, i become 80 kg from 110 kg but i earned my normal weight after next 1 year. I did very wrong things at that harsh diet; unhealthy drugs, long days without eating only water etc.

Anyway, after i earned my 30 kg back, i went in major depression and i didnt go outside of my home for 1 years. It was like nightmare and i become very silent person after these days. I was feeling big shame, i become freak legend in my highschool years. So i had to complete it from my home.

But, i wanted to attack again and destroy this depression years. I have started to work to university application exams in my country and i did national degree. This year is first year at my faculty. last week of september 2013, will be my first week at there. However, i am still 110 kg... I look like trolls in rpg games, some nights i just cry like an idiot due to my past. It is pathetic and i know it but i cant stop myself anymore.

In last months, i tryed harsh diets again. However, i couldnt do them again. My body gave big reaction and couldnt stay without emergency fast foods.

I guess, i cant lose +10 kg until school start day. So i should stop doing harsh diets and start to more realistic and healthier diet with long time period. I want to be 90 kg at 2014.

I dont know how to cook, i only consume fast foods due to my family's eating habits since my childhood.
However, i need a diet program for my aim. I need someone's help to me.

Can someone make a good program for me? Like eat this at this day and eat this at other day etc.. Diet program.
I could be so happy and my life could become better if i lose my extra weight.

I know it is little bit being spoiled, but i really hate sports.. I only do walking some days, for 45 minutes, except that i just stay at my computer or read books.

Sorry for long text,
Good bye.
