Misdemeanor Embezzelment Charges

My question involves criminal law for the state of: Michigan

I'll try to keep this as simple as possible, but that might be difficult, especially for a novice. Lived in Michigan (in a very conservative area), about 4 years ago and went through a divorce involving children. I had my own business there that I simply could not continue to run myself and used clients money to pay for child support because the money was running out and I had no where else to go. I'm very upset I did it and it weighs on me everyday. My ex had no job and I couldn't let them go without food. I moved out of state to get a job making good money and to be able to support them in my field of expertise.
I was contacted by a detective and I told him what happened, but they put out a warrant on me.
My job demands an incredible amount of hours and I live too far to get there in less than a day so I let things go. (Bad decision)
On one visit up to see my children I was pulled over for a speeding ticket and DUI. There was a $250 warrant for this case and I paid both and went back to where I live. When I had to appear in court to take care of the DUI, they arrested me for not showing up and I had to pay $500 this time, but I had to get back down to work again. I had no choice or would have lost my job.
Anyway I'm completely done with all the DUI issues, which are mainly money, and now I want to get this overwith.
My question is should I just go up there and turn myself in? I have an attorney up there, but he seems not to be concerned as much as I am! Maybe because he has $1,500 of mine? I don't know if this helps, but this client readily admits I did wonderful work for them over a period of time and my ex will write whatever is needed to help the court understand the position I was in.
I thought about calling the party that I did this too and just pay them, since money is not an issue, but I was told that will not help.
If I go to jail, I will lose my job, and then can't support and it's a slippery slope so I've been putting it off for obvious reasons.
Help.

Whether and when to turn yourself in is something to work out with your lawyer. Talk to your lawyer about negotiating an up-front deal with the prosecutor that includes your payment of full restitution.

Thank you for the response. I have done that, and his e-mail response is that I must turn myself in first and let him know when. He does not seem to be gameplanning on my behalf at all.
