I don't think you're alone in this. Most people, I would wager, feel like their life is a loop.

Wake up, go to work, come home, relax, go to bed. Rinse and repeat.

I think what you are saying, and I could be wrong, is that your loop is filled with pain. My suggestion, and please take this with the best intentions, would be to find something you can do - either creatively or physically - that you can do to try and "shock" yourself out of your cycle. Try painting or playing music or writing.

I believe the best therapy is engaging in some sort of creative activity.
