Why do everything makes me extremely angry?

[LittleCat88]

So these past few years I have been extremely angry due to several problems occurring in my life.
I was in a bad relationship where I was blindly in love. I would literally do anything for this person and, in return, he would call me "fat" or "dumb". That's where I developed an eating disorder because I would spend days drinking only water. Then we broke up because we were not happy with each other anymore and I started a relationship with another person.
After a year in a good relationship, he left to another state because of a job. I was broken once again because I felt I was left behind.
Since then I can´t be in a real relationship with anyone else.
I lost my job as well.
I was robbed yesterday.
And a guy I was going out dumped me today.
The friends I thought I could rely on are not real.
And I can´t smile. Never.
Will this end?
