accidently missed court date for child support modification

My X husband filed for a reduction in child support. I was unable to afford an attorney, so I did all my filing on my own. I filled a memorandum in objection to the reduction. I filed an objection to his financial affidavit as he was hiding income, I filed my own financial affidavit and a motion to deviate from child support guidelines. I requested today off to go to court and then found out it was yesterday. I wrote down the wrong date. My father has recently passed away and I have had to do an appeal with the VA for my mother regarding her benefits, do all the work for the asbestos law suit, I had to go thru an appeal for COBRA and it just got settled last Friday in my favor and I have 3 children, a job and a home. I have the children over 80% of the time. I honestly just got the dates confused. I was told I could file for a rehearing within 10 days but do not know how to do this or what to put in it. Can you please give me some advice on what to do?

Usually if you go to the courthouse in the area where the case was/wasnt heard and ask them what you need to file, they will usually give you the papers to file. Hope this helps!
