I still us Jehovah....
Probably will for the rest of my life.
I don't allow the WTS to have exclusive rights to a name that was decided upon for the English rendition. Jehovah is found in other bibles, used in sermons by other preachers, and found in many hymns....... I also don't allow them to dictate the relationship I have with Jehovah or Jesus because their claim of appointment upon reading older literature and seeing the revision and claim not being made until way after 1918-1919 proves that it is a myth and sham!
When you are ready, find a quiet place and pray, turning it all over to them, asking for holy spirit to give comfort and guidance (it will be emotional but when you are ready it will also be a deep release).......
I did like Isaacaustin's suggestion of 'Father'...... or perhaps "Heavenly Father".
Don't rush, breathe
I am in a similar boat of family being close and highly involved with livelihood, childcare, and housing.
I am still attending but knowing the truth about the 'troof' gives some comfort.
Just focus on getting that divorce and taking ONE step at a time.
