Too much time to think

On days when I have too much time to think, my mind sometimes gets the better of me. I get sucked into this neverending circle of what if's and why me's. I'm trying my best every day to NOT let it get the best of me...to continue to look on the bright side of things. To not just give up. I'm just so tired. So tired of never being the one with the good news. And then, I get one moment of pure excitement...and it's taken away and I'm left right back where I started. Someone just slap me and tell me to just get the hell over it. UGH.
