LG I will not claim to be any sort of daas torah and obviously you shud ask your rav what the halachos are.my point is that I dont want you to walk around with guilt that you don’t FEEL Respect towards your parent. In regard to how to ACT with respect, speak to ur Rov about the halachos as it is very important to have clarity in this area.
kibud av vaeim is a mitzvah that applies to all and is so importany. Like oomis said, it’s not a mitzvah to love ur parents however we do have guidelines in how to relate to them. And there are guidelines for all situations..yes it’s often difficult..
