What if I feel like my life is over now?
That's sad. Why do you feel that your life is over?
I can't figure out what I should do to change things and get out of a bad situation.
I'm sure that you feel very frustrated and ready to give up, but you can still change things and find enjoyment in your life. You should talk to a professional that can help you make a plan for your life and find something that makes you happy. Giving up is not an option when there is so much help available for you.
No, I can't do talk to anybody. I don't feel like I have anything left.
Sure you can, it is just talking and it will help you so much. You shouldn't give up  just because you feel you have  nothing left.
