I feel like I'm trapped and I can't get out
Why do you feel trapped?
I can't imagine a way for myself out of this situation.
If you're feeling like you're trapped then you should try and get some help with of the situation. Any time that you feel trapped in a situation you should do your best to leave it before things get worse, and others can help you.
You just don't get it and people like you are the reason why I feel trapped. If I could leave, I would already be gone.
I can understand your frustration, and you're right that I should have inquired more about your circumstances.  However, even if you can't fully escape from this situation, you can make it better, and possibly even take steps toward a brighter future.  If you let me know more about the specifics, I can offer some suggestions.
