I'm going through a break up...

I am so hurt and broken and depressed.

Everyday I wake up sad and empty. When I do I start to pray and I pray continually through the day when I feel like that.

At night I feel the effects of the break up more and I get really sad. Sometimes I cry but I mostly just pray.

I'm so tired of praying and not feeling that much better from my heartache. I'm exhausted  and hurting from having my heart broken, from being sad and depressed and I want to disappear. This is 4 months since my break up and I just want the pain to go away. Sometimes my mind gets so heavy with my concerns and from praying so much that I just stop. I'm too tired to continue.

Is is possible to get tired of praying and seeing little to no result? What should I do when I feel like this?

Edit: I am praying for my heart to be healed.
