Millions of people over the centuries have converted to Islam and they have solved problems like these. I am sure you can get help. I will do some research and let you know inshallah. There is one Dr. Hamidullah one of the greatest scholar of the last century who lived in Paris on whose hand 80,000 people converted to Islam. I am sure you will find solutions from past examples. My best wishes and prayers for you to prosper and stick to the true faith of Unity of God and following the great humane pristine teachings of Islam. Amen.
I encourage you bond with a muslim friend and family. Sharing and discussing our problems in general with someone trusted brings out some good solutions. Learning from your fellow brothers and sharing the good of that with your family may change your family's hearts as well. In Sha Allah. May Allah help you. Ameen.
Dear brother wish you the best. One thing you can do is not mention Islam to them or pray in front of them. If you are going to the Masjid just say that you are going out. Don't lie but you don't have to tell them exactly what you're doing either.
