Where is my "Happy Ever After"?

I'm stressed. I need a break. I don't have anyone to help  me...my support system is flawed. One of the biggest stressors in my life is my heart. On top of everything that has happened in my life, the one thing I prayed would work out at least was my love. And yet, I'm still alone. And my heart is still broken. Even though nothing else was going right, when I was in love, I felt like I could some how make it through. And I felt God was watching over me, because He gave me such a strong and powerful love, in spite of my trauma, the depression, the bad eating habits, the people walking in and out of my life, and everything else. Even after life had did everything to ensure I wouldn't ever know true love, I still found it...........and in the end, a bunch of petty stuff got int the way, and now he's with someone else. And I am alone. Now...I'm barely making it through. I have so much emotional baggage.....everything is telling me to give up. Everything is saying that I am foolish for hoping and believing I can be better and have a better life full of love, joy, and success. Everything wants me to stop trying so hard. I'm wearing myself out, and for what? Everything wants me to believe that nothing good will ever come from all the effort I am putting into my life........but even after being hurt over and over, after my hopes being slam down to the ground and crushed over and over.....after failing and losing over and over, even still, there is something on the inside of me saying I can make it. There is something on the inside of me gently pushing me and giving me strength. Sometimes I get so mad, because I don't want to try anymore. I'm tired and want to give up, but I can't. And because I can't, I feel so angry because it feels like I will never get to my "happy ever after."
Why do I keep trying? Why can't I just give up?
I know it's God who is pushing me, but if He wants me to keep doing well, why wont He let me be happy? Why wont He finally start giving me the fruits of my labor? Why is it still hard? Why wont He give me love? And stability? And peace? Why do I keep crying? Every time I get better, something else comes and I'm crying all over again. If He really wants me to be strong and keep pushing on, why doesn't He let me have some of my hopes and deepest desires now?
When will my "happy ever after" come?
