As others have said. It doesn't seem like you are at a good place to tackle weddings.
That type of photography can be very demanding (as are most brides) There is so much that needs to be addressed beyond the photography itself such as meeting with the people that control the venue and with the MC (priest, rabbi, ect).
If you are doing this for a friend/family member, failing to meet their expectations could irrevocably damage your relationship with them. If you are doing this professionally (for strangers in exchange for some form of compensation) failing to meet their expectations could result in lawsuits that can be nothing short of life-crushing, especially if you are not properly licensed and insured.
