It is important, for example, to discuss your feelings openly. It is common to experience some moments of doubt or fear of the unknown. It is also vital that you stay in touch with your birth family. Converting to Judaism does not mean you are abandoning your family, your friends, or your fond memories of past family life. When discussing conversion with your family, explain your reasons to them directly and tell them of your continuing love.
Most families are supportive, often to the surprise of the person converting.
Some families, however, do need reassurance and to have their questions answered patiently. There are also, sadly, some families, who see the conversion as an abandonment. At some point in learning about Judaism, preferably as early as possible but especially as you get more serious about actually becoming Jewish, you should talk to a rabbi. Some traditional rabbis may actively discourage potential converts by turning them away three times. This is a test of how sincere the would-be convert is in wishing to become Jewish.
