In my experience, obsessing and stressing out over how much your life sucks will just make you more unhappy. I've been there and done that, and I made myself miserable about things I had no control over.

Make a list of the things that make you unhappy. Divide it into two groups...things you can change, and things you cannot. Work on the first list, and shrug off the second. Find things that make you happy. At worst you have maybe a few more years in this situation, and I know that seems like eternity now but believe me, it's nothing.

The best thing about living through hell is that you can look back and laugh at it all; and when life gets rough you'll know you can handle it, because you've already been through the worst. I spent three years with an abusive, dishonest, deceitful husband. When I think of all the things I went through, nothing in the future holds any worry for me, because none of it can possibly be as bad as what I've already survived. And if I can survive that, I can survive anything. You can too.
