Getting through a divorce?

Hi iam currently going through a divorce. Its been nearly a year now since my wife asked for one. I had to agree as it was pretty obvious that it wasnt working - no and comunication. To tell the truth it was a big relief and good to stop living a lie. I am certainly not trying or want to go back there. My question or dilema really is that i am or i feel like i am drifting, i mean its hard to concentrate and even get out of bed. I look at somr of my old wedding photos and its not that i miss her but i miss being that guy so sure about what my life was .. i mean i was a husband, paying a mortgage .. well now im just some guy who is drifting really, and i guess my question is is this what my life looks like now or does it get better. A friend of mine said to me he thought i was ready for another girlfriend or companion but i mean i appreciate the sentiment and yeh of course im better than i was but still i am drifting like i said. Oh yeh it doesnt help that i owe the x circa 20k for a family loan which is no problem but it certainly adds to this feeling of limbo .. any advice please or has any one else been through this
