I am very much encouraged that despite so many difficulties and tricks of Maya that you are still desiring Krishna so much. Thank you very much. In order to attain the topmost perfection of this human form of life one simply has to try for Krishna with enthusiasm and patience, and all obstacles will be overcome. If you are determined in this way to be His devotee, Krishna will provide some happy solution. But even if He puts us into extreme difficulty, we must always be prepared to consider everything as His special Mercy, that He is testing my sincerity, or that this trouble is nothing to what I deserve. Just see Prahlada Maharaja. His father tried to kill him many times! At least I don't think your father is trying to kill you. And after Krishna in the form of Lord Nrsimhadeva came and killed Hiranyakasipu, Prahlada prayed to Krishna to have mercy on his demon father. So we must take the instruction to respect our parents, and to be kind and very tolerant and patient with them, and very soon I promise you everything will be all right.
I am very pleased that you are chanting regularly. This will save you and protect you from all misfortunes. So chant Krishna's Name regularly, think about Him all the time, and your love for Him will keep you free from any bondage. Also, you must try somehow to avoid eating any meat, fish or eggs. Be very strong in this respect, and eventually your parents will appreciate your determination especially if you are otherwise always very kind to them.
