Lately I've been feeling like I'm trapped in my relationship.
Would it have anything to do because you lived together?
Yeah, it's not really what I wanted.
I'm sorry you don't feel safe in your relationship. But, you can't keep such feelings to yourself because communication is always key to a healthy relationship. If you don't want to break up tell them how you feel.
Maybe I should think of killing myself.
Now, that is going way too extreme. If this is making you feel that bad and I think it's time you discuss with your girlfriend you are not happy with the current living situation.
