Earl, I am sorry to hear about the deaths in your family.
It sounds like they are blaming God and, because you are the one committing your life to Him, they are taking it out of you - the next best thing in their eyes (what a compliment!). When you commit yourself to Him you are going to be faced with all sorts of problems as a result of that commitment.
The first thing is for you yourself to understand the meaning of death. A believer can come to understand but a non-believer can never understand. That is because they don't know the reason (purpose) for their own existence.
Because you are the lone believer the lot falls to you to pray for the souls of the deceased. This refers to the situation in the death of a Catholic but it may help you to go through this difficult time:
http://traditionalcatholicteaching.com/lesson19-death-and-after.htmlThey are obviously searching for meaning in all this, so they seem to be among the first group that I mentioned, even though they are at present showing negative attitude towards you, your Faith and Your God. Your steadfastness will help them, even if it seems to you, you are not performing in the way you would like to.
Have you been able to do anything about your Baptism? It is rather a pressing matter, and because it seems that it will be impossible for you to attend a traditional Catholic priest, I think you should consider a visit to that bishop who was concerned about the Latin Mass being available to the people who desire it. You could explain your situation to him and see what eventuates. He may kick you out on your ear, but it may also tip the scales for him. Bishops are only human after all. A visit to him would not hurt, though I would not recommend that you attend Novus Ordo masses.
