In need of some serious help....!!!!!!!!

I live in Michigan and last night all our streets we're pretty much flooded from rain and melting snow. My car got stuck in about 3 feet of water. My engine was pretty much out of the water but the back end, not so lucky. I had about 8 inches of water in the back driver seat and about 4 in the front driver seat. We finally got it in neutral and got it pushed out of the water. Got most of the water out of the interior but had to leave it at a Honda Dealership over night. Today i went to start it and take it home and PFFFFT nothing....the chimes come on the speedometer etc. lights up and all the inside lights work fine. My head lights will not turn on though? The sidemarkers are fine as well. We tried jumping in numerous spots according to the manual and stuff. We checked the fuses and they are all fine. WHAT HAPPENED???????? I am in serious need of help....if you have any advice pleaseeeeee POST IN THIS THREAD!!!
Thanks
