Pleaase help me find my Daughter

Almost eight months ago my mother was diagnosed with stage 4 cancer of her lungs, liver, lymphnodes, brain and adreanal glands. When diagnosed my fiance and I decided with the help of friends that we were going to do everything here at the house because that is where my mother wanted to be. For the next 6 months my family endured and are still enduring the most servere hardship of our life. Nearing the end my mothers life my fiance was not effectivly coping and left with my daughter. My mother died 2 days later. We went through the motions of working out the burial arrangements. Only one of the small insurance policies went through so the head stone still needs the paid out of pocket with everything else going on. I have attempted to contact my fiance via cell, facebook, and friends with no response. I have been extreemly empathetic and sympatheic to her situation being my mother was a good friend of hers. I however in this time of drastic pain I need my familly. To be honest I do not know what the status of my fiances relationship and although that is very important to me my proirity is finding my daughter. Her Name is Shayde  she is 2. At this age the development of her personality is increases by the day and I am not able to be apart of that. I have contacted many agencies and here in Florida my rights and opitions are very minimal at best. I would use the funds to retain a lawyer and a try to locate her so we can begin civil custody. If requested all receipts can be emailed or verified how ever requested. I do have a job and I work full time. I am not a drug addict. I am a great father to my girls and that is what I live for. This is a very time sentive matter seeing I have exhausted all funds for bills for the house I currently provide for my other 8yr old daughter in. The longer I wait the colder the trail will be. Any support given will be directly invested in this and this alone. In other words you will not be contributing to my electric bill. I can not express in words how appreciative and greatful I am for your generosity in this matter.
